Ducati Monster Forum

might be a good idea to revive this thread from TOB. seems like folks are always asking. maybe sticky it to the top in tech or FAQ??

i will do a little cut and paste to get started

General rule of thumb for all "steel" tanks goes like this.

They're backwards compatible. If you've got an older bike and are trying to fit a newer tank it will fit, but might need a few mods or a change(s). Unfortunately putting older tanks on newer bikes will take more work than most will want to do/bother with for either PITA factor or $$$.

Specific differences are below

from 1993 - 1999 All the carbed tanks fit the same (but the cutouts for the seat are different from the newer 2000+ designs) and they only have 1 fuel line coming out which uses either 5/8" or 8mm fuel line. All steel tanks have 2 drain lines which are 1/4" or 6.35mm sized lines. All carbed models have their fuel filters/pumps outside the tank. You can use a newer tank, but you'll have to also use a newer seat to fit the cut out of the tank (it's only a little off and if you're not a perfectionist, it's livable)

In 2000 & 2001 Ducati made both carbed and FI tanks. The most obvious difference between them is that the fuel filler on top either has just a fuel cap (for carbed models) or a fuel cap which is just inside an aluminum ring (for the FI models).

(FI) All FI tanks have their fuel filters and fuel pumps inside the tanks. And you would remove both the fuel cap and the aluminum ring which the fuel cap mounts to from the tank (gently using the wooden handle of a hammer) to gain access to both the fuel filter and pump. It helps if you've got small arms to fit inside that hole. On the bottom of these tanks there are 4 lines coming out. All 4 of which are bent at 90 degrees. 2 are large for fuel (5/16" or 8mm) and 2 are small (1/4" or 6.35mm). The cut out underneath for the airbox and battery are different than the newer design and will NOT fit newer tanks without a lot of relocating of parts or modifying.

(carbed) These are the rarest tanks as they are for carbed bikes and have the newer seat cutout (which fits everything from 2000 to current in the Monster line), but are have the smaller hole at the top of the tank for only a gas cap and NOT the extra aluminum ring. But it's fairly easy to make any FI tank fit this bike with a little work. Closing off one of the fuel lines and adding the extra aluminum ring (which didn't come with the original carbed tank) and has 8 2mm allen bolts holding it into the tank.

All tanks from this point forward are FI only.

The 2001 S4 tank is special as it has the underside shape of the newer 2002+ style tanks, but it came out in 2001. (FYI- this was the first Monster to use the ST style frame and 5.9 "immobilizer" electronics, all Monsters going forward use this)

From 2002 & 2005/2006 Ducati also went with a different location for the battery and airbox underneath the tank. So the cut out underneath is larger overall (hence why the older tanks don't fit) also the fuel filter is held inside the tank with a C clamp in these tanks, rather than just floating in the previous FI tanks. The easiest way to tell the difference between a 2000/2001 FI tank and a 2002/200x FI tank is by the fuel lines coming out of the bottom. Specifically the 2002/200x tanks have 4 lines coming out of the bottom, but only 2 are bent at 90 degrees (the smaller 1/4" or 6.35mm ones) are bent at 90 degrees and 2 the larger (5/16" or 8mm) ones point straight out of the bottom towards the ground when on the bike.

In 2005/2006 (in the US at least) all the tanks went to plastic. (But there's still a few Metals that were being depleted from stock, hence the 2 year span to actually completely change to plastic) simple check to confim, just check to see if a magnet sticks to it. These tanks have the same cutout underneath for battery and airbox. But have a different fuel filter/pump system that bolts into the bottom of the tank. They only have a gascap on the top of the tank and they use a different mechanism for the hinge.

2007 From what I hear, the S4RS tanks are very differently shaped too. But I've not seen one to tell you what those differences are compared to others.

Can we get some pictures of the undersides of the different tanks?

Specifically:
1. Plastic underside with good view of the fuel pump set up
2. Carbie tank with a good look at the fuel line connections
3. Injected tanks (various models) with a look at the shape and fuel line connections
3. different hinge styles (plastic Vs. metal)
4. Anything else that folks think is important / relevant

I have pics detailing the connections of  FI steel and CF tanks, are we going to get a gallary and pic upload facility?

nope. need to host pics on another server (photobucket, etc...)
 wt:

Can a mod please sticky this thread  ;)

Thanks

Don't forget the easiest way to tell metal from plastic without touching it is to look where it rests on the frame. The metal tanks have the pinched together seam, the plastic tanks do not...

are all fuel caps interchangeable throughout the years?

obviously the 2001 onwards have the aluminium ring...they all have 5 allen/hex bolt on the outside?

also, does the external shape of the tank change in that 2002+ (& onwards) ? the knee dents are more forward aren't they?

1) Yes, you can use any cap for any year. And only 3 outside / 1 inside bolts are needed. the other 2 outside bolts are just for looks.

2) The knee cut outs only changed in 2000, and the newer ones are all the same. And for the record, you can use one that doesn't fit, but it's just  not perfect...

i think the biggest difference is whether the fuel cap comes from a carbie or a fuel injected bike. difference being that the FI tank requires the outer metal ring, inner metal plate, and a rubber gasket, which are seperate pieces from the actual cap, while on the carbie most of that stuff is already part of the tank.

The cap assemblies are all the same

thanks guys - I'm going to buy a 1098 cap for the monster - they are charcoal grey and will match the carbon better. Thanks very much....

having said that - I'd kill for a vintage Cagiva fuel cap with the elephant on it, tres cool!

Spider

uh, your original post didnt specify a 1098 cap...
not saying it wont fit, but that does change the question a bit.

anyone with a 1098 want to chime in on this?

well, they are the same diameter, same 5 bolt patterm...so two out of three ain't bed!

then we just need the little leg that screws into the shelf of the tank to be the same...of and the locking mechanism too...

aaaghhhh...It'll never work!

I'm thinking of upgrading my older carb engine (98 bike) with a newer FI engine.  Will I have any problems matching my current tank to the newer 1000cc DS engine? 

You will need to swap tanks and the seat to a 2000 or newer combination.

I'd recommend steel over plastic due to capacity.

Thanks, but what are the problems with the old tank?  Are there Clearance issues?  One fuel line coming out of the carb tank two out of the FI tank, is that the issue?  I'm just wondering if I can overcome the problems with ingenuity, a welder, and a hammer [laugh].   

The Ducs use an internal fuel pump rated at ,I think, about 80psi and a pressure regulator on the TB.

You can use your old tank/seat if you use an external pump and can fabricate a return into the tank....and fit a filter capable of handling the pressure...and a pickup screen to protect the pump from debris....

Which is easier?   ;D

Thanks Ducpainter.  This is sounding like an expensive hassle.  Another tank plus chucking my Corbin seat.  My 98 monster has an external fuel pump so it may not be a big problem to replace it with a pump that meets the specs, but fabricating a return.  Oh well, it was an idea. 

It frickin works! a fuel cap off a 1098 goes in....I now have a hybrid - part Monster, part 1098....sure it's a small part but still.

actually the 1098 (new) cap was made with just standard alloy whilst the monster from 2003 had a heap of brass fittings in there! I'd previously heard/read about Ducati changing/degrading bolt quality in 04.

spider, you have pictures of this masterpiece?  I have an SS that told me to get her a new cap.

here's the 'evolution' of my very stock 1000s - there is a post in there regarding the cap - for you to use (use big sheet of white paper and tweezers when doing the cylinder swap)

http://ducatimonsterforum.org/index.php?topic=1168.0 (http://ducatimonsterforum.org/index.php?topic=1168.0)

looks a lot like the stock fuel cap on my bike.....

FWIW........why not look into the aftermarket stuff available.
there are some really bling fuel caps out there

My Oberon cap from Motowheels...

Ok even after reading this great and informative thread I am not sure if my tank bike combo I am thinking of doing will work.  Any help would be greatly appreciated. 

So will a 2000 M900 Dark tank (not that the color matters) work on a 2001 MS4?  I am trying to find out before I try and put my old dented M900 tank on the S4, so that I can paint the current S4 tank and not miss out on any riding!!!!

Thanks for any help.

The earlier 2V tanks won't work on the S4.

Interference between the tank and either the battery or the vertical head.

Crud, that shoots that idea.... DucPainter, thanks for the help!!!

If you can get an '03 or newer steel tank that will work.

Now there is a thought!!  Cool thanks for the idea, after seeing how good Scooby's looks as a dark though I have some thinking to do again.  Thanks again for the help Scooby, and DucPainter.

Cheers from Colorado!

Anyone know what I'd need to do to get an '06 S2R plastic tank to fit on a '02 900 frame?

New brackets?
Fuel pump?

Will it even fit?

It can be done, but it would be cheaper to get a used steel tank.

You'd need a new hinge bracket, and the entire fuel pump mount flange which includes the pump, filter. and sender.

I am trying to remove my fuel level sensor and i can get my hand on the connection inside the tank but i dont know how to actuate the clip on the connection.

 Do you have to press the little clip towards the housing of the connection or depress it outwards to remove it?

 See picture above to see what im talkin about.

Push it towards the connector body.

DP's right, but my fat knuckles have a hard time workin in there.

Instead I take out the whole pump/screen assembly and then unclip the senders plug from the pump once it's outside.

Just my 2 cents.

if my fuel level sensor wires have some of the outer insulation scraped off.

 should i use it? No metal is exposed but its down to the white inner insulation.

 Is there anything I can do to patch it up?

Hi Herm
Im having issues with my tank. I bought a new tank and have the underside images of both.
Its for the carb models, to fit the early to mid 90s models


this is the new

what confuses me is that the description of the tanks say that there are 2 drain lines and 1 fuel line. this is fine for the old tank. but with the new there's and extra line which looks to be a third drain line?? a few min after fuel is put in it comes out the third pipe.

To fix this im thinking i'll get a T or Y connection and just link that into the main fuel line

I hope this helps
Dom

They use tape at the factory to hold the wires together...

but I wouldn't worry if the copper isn't showing.

According to the fine print " ....Except Plastic tank models"....you've confussed me more my brother.... ???

For the 06 model year, Ducati Monsters came with both steel and plastic tanks. Some came with steel until those ran out at the factory and then they started installing plastic ones. So it's a reference only to the last year, which they may or may not fit, depending on the type of tank the '06 bike in question has.

Well my Bike has a plastic tank and according to the VIN is a 2005....Now I need a tank, and if I can get one metal one, better...mine cracked in the accident and didn't notice untill filled up to test ride... :-[
Anyone has a metal tank...for my bike, 2005 620 Dark... :'(

Sorry, I said 06. 05 is when the change from metal to plastic started. My mistake.

You can't use a metal tank without also buying a new fuel pump, fuel sensor and a couple of other parts. Metal tanks may not crack in an accident, but they dent very easily in low speed tipovers. I looked at switching over the other way and decided in the end it's easier to just buy what you have now.

good questions, and answers.

the important thing to take away is that the s2r1000 and the s2r800 can be fit with a metal tank, even if they came with a plastic tank. however, the metal tank needs to be from another FI bike (and not an s4r), and you would also need the plumbing for that tank, as well as the hinge mechanism.

I'm looking into adding to my garage a 2001 S4[guy is leaving the country and doesn't want to take bike with him], the tank was rusted thru on top, everything inside is ok, can I fit a plastic tank to it or should I just buy a metal tank from which model then?  I'm dumbfounded. ??? ??? ???

Get steel....

2003 up steel will work...or an S4.

thanks ducpainter  [beer]

+1

+2 on the steel tank, as long as you can find the right one. there are too many problems surfacing with the plastic tanks IMO.

Just to clarify "what the right tank for your bike" is.
(this is for any/everyone that wants to swap from their current plastic tank to a steel tank. the only exception is the testa engine Monsters as they're VERY different underneath)

Any steel tank from 2002 or newer or a 2001 S4 tank will work fine as long as you also get the fuel pump, fuel filter, gas cap ring and hinge assembly.

The tanks that will NOT directly fit are:

any carbed tank or any M900 FI tank from 2000 or 2001

Thank you very mucho... Now I've seen some  more ligth on Ducati...

Anybody know if a newer generation monster tank will fit an S2R model ?

If you mean 696/1100...

no clue.

Yes thats what i mean ....
I dont care for the plastic covers, i just like the way its cut around the knees

lots different about the frame.
thicker, steeper angle off the seat, attachment...
i would wager no, but WTFDIK

So according to this, I can fit a 2002 M900 tank on my 2001 S4, Correct? That's how I read it but I wanted to be sure before I bid on one on Ebay.

The carbon tank is different than the steel.

I think you need an '03 or newer steel tank for the S4.

I might be wrong.

That should be correct. I have an '02 M900 and when I was looking at new tanks for it I was told an '01 S4 tank would be an direct match. They have the same gas tank internals, frame and they use the same air filter box, which determines the cutout under the tank, so it should be an exact match.

Great Clarifications.... Good info for all!

Ok, after reading through the thread I have two questions.
1) is an 07 695 tank any different than the +02 monsters?
2) is an 07 695 tank plastic like the new S*R or metal?

Both, plastic... As long as is not an S4RST ...It's totally different. downloaded all parts catalogs from Ducati webpage and compared tanks, S4RST, not compatible with any other except S4RST.

Couldn't you use the fuel pump and filter from the plastic tank?  Or am I missing something.

No, they're very different components. Also the hinge that the tanks connect to is different.

At least the gas cap is the same. Dunno about the latch assembly or the rubber blocks.

so the inside components are different between the metal and the plastic tanks, what about just the 02+ metal tanks? are the guts interchangeable amongst just the metal ones?

latch assembly is the same.
i believe that the internals on the metal tanks are all the same.

all metal FI tanks use the same internals (regardless of what year) the only minor difference is the length of the internal fuel lines as the 02+ tanks have a clamp that the fuel filter goes to. But the guts are the same.

VERY IMPORTANT NOTE: Make sure you use the submersible fuel lines for the inside. I forget the model #, but it comes in 5/16 aka 8mm and it's mean to be used in FI systems while being submerged in fuel. ***Most fuel lines are not meant to be submerged in fuel***

And the fuel sender is different for the carbie tanks, but the same for all the FI tanks.

If they use, or in the future, will use E10 fuel in your area, you need SAE 30R10 hose to resist the ethanol.  Not easy to find and expensive.

Thanks for this. Never heard you needed different fuel lines.
That explains why my overflow hose sprung a leak for no reason.

YW,
Now the difficult part is finding 1/4" aka 6mm lines for the overflow. I have NOT been able to find submersible fuel line in this size. If you do please pass that on.

In the meantime, the only thing which will work is the Duc stuff from the factory... ugh!

according to this statement, i would then assume that this tank pictured would be from a 2002+



this is the tank itself:

thoughts?

i cant see any of the fuel lines in those pictures, so i'm no help

maybe the pics arent showing up...

I don't see any pictures that show the fuel lines in the actual ebay item.


But the pictures directly above this post are for a 2002/200x tank. 

thanks! its the same tank, i had the guy send me the underside pics because he couldnt tell me what year bike it was off of.

Please forgive if this question has already been addressed, but there is more info here than time to sift through it all.

Who has experience with the DP Carbon Fiber tank?

I've had my plastic 07 S4RS tank replace under warrantee, but thinking long term.  I doubt Ducati has fixed the problem with swelling so I want to know what options I have.

Are there any problems with the Carbon Fiber tanks?  Swelling?  Fitment?  Leaks?

Thanks in advance for any info.

Some of the DP tanks were relative junk....

literally falling apart....at the seams. Ask Dragsterhund.

I honestly don't know if the problem has been rectified.

I think I have read this thread so many times, it isn't sinking in anymore. 
Still have a question though, will a tank from an '04 s4r (steel) fit on an '05 s2r?   ???

Thanks.

You'll need all the internals and a frame bracket (bolt on bracket) for the steel tank. You'll also need the large bung that the cap bolts to

What does this look like and what is its purpose?

On a plastic tank the part on the tank is like a tube and the bracket on the frame has two ears.

On a steel tank the bracket on the frame is a tube and the tank has the ears.

Best I can do.

DP,
I'm not finding anything like what you're describing on the parts fiche from Ducati.com.  What is the purpose of the frame bracket you are describing?  I'm sorry for my ineptitude on this subject.  :P

The pieces that DP is referring to hold the tank to the frame, right where the seat is. (Basically where your nuts would wind up if you grabbed a handfull of front brake). it's just different between the plastic tanks and the metal ones.

(http://farm5.static.flickr.com/4040/4386698289_602ae7235f_b.jpg)
In this image the bracket is #19

(http://farm5.static.flickr.com/4007/4387457004_9c0becdbf0_b.jpg)
The parts you'd need are  #22 and 23.

You also need #16,18, 19 (x8) and 21.

The associated pins and bushings may or may not work from your plastic set-up.

here is a picture showing the difference between the plastic and metal tanks. sorry the metal tank pic is not better

(http://i299.photobucket.com/albums/mm285/s2r1000/382.jpg?t=1267134333)

AHHHHHH!!!! Thanks guys!!!  [thumbsup]

I was looking at that micro fiche, but didn't recognise those parts for what DP was talking about.  Thanks for clearing that up.

Went  through the entire thread.  No definitive answer for 2007 Ducati Monster S2R800 compatibility.

I have a 2005 620 and was wondering if a 2007 Ducati Monster S2R800 tank would fit on it?

2005 M620 tank       586.1.044.1[CA>Red/CD>Met Dark Grey/CT>Black]
2007 MS2R800 tank 586.1.044.1[CJ>Redw/white stripe/BT>Black]

So, yes it will fit . . . ;D

If your tank is plastic it will fit

I just realized that my bike is a 2005 but it has a metal tank so i guess its an early 2005 with a 2004 metal tank?

I was planning on purchasing a new tank but now I am confused on which tanks Im limited to and what I have to do about the fuel pump because it is not the same as the one in the 2005 diagram.  The system I have looks more like the one in the 2004 diagram.  =(

fuel pump, hoses, etc..  and hinge are different between the metal and plastic tanks, but the gas cap and latch are the same.

Thanks guys.  So basically I am restricted to finding a 2002 - 2004 metal tank.

Because the pump on the plastic tank cost more than teh tank it self.

Regardless of relative cost, you don't want a plastic tank

Who does?

Hey ,

I am just making some research for my winter cafe project . I 'd like to build a "cafe fighter " from a 99 monster 750 carbed model.
Can somebody help me out if any of the SS carbed tank will fit on the monster frame? I will make a cafe tail to line up with the tank ,but the fuel tank is a bigest issue.
Thank you guys

I just want to reaffirm my decision:

'01 M900 steel tank (fuel-injected). Seeping fuel from the flange that's tacked to the bottom of the tank. I am going to have it re-welded. My intention is to remove the fuel pump & filter.

Is that necessary?

remove the those and the filler cap . . . and wash it thoroughly !!!

Also remove the sender.

You should really consider coating the tank with POR-15 after welding.

Thanks everyone.

First issue: How much force does it take to break the aluminum ring loose from its seal? I remove the filler cap assemble, but the ring is really stubborn.

They can be a bear.

Use a hammer handle stuck in the hole as a lever. If you can, get some WD-40 or other penetrant under the black gasket and then hit the head of the hammer with one hand while using your other hand to protect the tank. It will pop loose.

Grease the flange and o-ring on reassembly.

Hey guys.

I've read through this thread twice, I just want to confirm the following;

I want to purchase a new plastic tank (2005 up to 2008) to fit on my 2000 M600 (carbed) frame. From what I gather, I simply need:

The fuel pump (which will replace my external pump duties)
The filler cap
A way to close off the return line

And it's as simple as that?

And if I go with an FI metal tank, I would simply need to close off the return line and source the inner ring, and use my existing fuel pump. Correct?

Thank you!

Are you using carburetors or FI?

I'm using a 00 M600 frame, a 96 900 engine,  FCRs with pods and Ignitech

 Thanks

Reading here it seems that;

Plastic tanks use their own pump. I like the idea of this as it is one more way to clean up the exterior of the bike.

The FI metal tank sounds as if I would reuse my fuel pump and simply block off the return line in the tank.

That is what I'm trying to confirm

All plastic and steel FI have internal pumps, but they're high pressure, not at all suitable for FCR carbs.

You can use the OEM style 'Mikuni pentagon' vacuum operated pump.

Some of the rectangular vacuum operated pumps will work, like this one:
http://ca-cycleworks.com/products/fuel-carbs?manufacturer=135 (http://ca-cycleworks.com/products/fuel-carbs?manufacturer=135)

Some folks have reported issues with that pump not supplying enough fuel for hot 900+ motors.
I've no experience with the rectangular ones.

Some folks have used external low pressure electric pumps, perhaps there's info in the 'replacement parts' thread.

You *may* be able to connect to the 'return' fitting on the fuel pump flange that's used on the plastic tanks.
You'll need to plug the 'supply' fitting.
But I don't have one at hand, so you'll have to confirm.

You'll need a front latch and rubber frame mounts, all of those from the steel FI and plastic tanks are interchangeable.

You'll need a plastic tank style rear hinge bracket, they're different from the hinge brackets for the steel tanks.
Might as well get the OEM 'upgrade' unit that allows more room for an expanded plastic tank.

All of the Monsters prior to 696/796/1100 use the same fuel filler cap assembly, that's all you'll need to have for a plastic tank.

Thanks. It was actually a different thread where I saw that Chris Kelley said the plastic tank would work on a carby bike.

Sounds like an easy job, either metal or plastic (provided the return line on the plastic tank works)

I already have the octagon vacuum pump. On another note I've wondered if the pump is even necessary with the FCR's....I wonder if gravity would do the trick.

Gravity will work until your fuel tank level reaches the same height as the fuel inlet at the carbs, long before empty.

From 2002 & 2005/2006 Ducati also went with a different location for the battery and airbox underneath the tank. So the cut out underneath is larger overall (hence why the older tanks don't fit) also the fuel filter is held inside the tank with a C clamp in these tanks, rather than just floating in the previous FI tanks. The easiest way to tell the difference between a 2000/2001 FI tank and a 2002/200x FI tank is by the fuel lines coming out of the bottom. Specifically the 2002/200x tanks have 4 lines coming out of the bottom, but only 2 are bent at 90 degrees (the smaller 1/4" or 6.35mm ones) are bent at 90 degrees and 2 the larger (5/16" or 8mm) ones point straight out of the bottom towards the ground when on the bike.

are you saying that these tanks will work on an 01 900 F/I bike? thanks

@doc_mon9
The 2002+ metal tanks work fine without any mods on the 2000 & 2001 bikes.  [thumbsup]

Hey everyone!

I'm new here, so here's a bit about myself: graduate student with a 1999 Ducati Monster 750. Unfortunately, it stopped firing in one cylinder about a year ago... and has been sitting ever since. Sad, I know. Please don't shame me too hard. I know. Point is, I finally found a place to fix it and am in process of fixing all the little things that need fixing (as well as the spark problem).

The tank is in really rough shape: when I received the bike the tank had the dreaded hinge-leak, was rusting and someone then tipped it over in a parking lot: signature Ducati dent! Savages.

Clearly finding the metal tanks in decent shape is quite challenging and expensive. But there are lots of plastic tanks available. It clearly seems like the metal tanks are preferred. However, I've read this thread thoroughly and deduced that it's possible to use any newer 99+ (plastic or metal) tank on my bike, with some modifications.

The tank on my bike now is gravity drained to a vacuum pump (outside the tank), so it seems like it would be totally possible just to remove the inner pump and slap the new tank on there but I'm just trying to feel out what modifications will be necessary and how much of a pain in the ass it's going to be...

Clearly I would need to replace the tank mounting hinge. (easy, $)
Potentially I would need to replace the seat, correct? (easy, $$)

What else?

Thanks so much! I look forward to the adventure of fixing up this bike and really making it mine.

Hi All,

Phil from Australia here, so my 2004 Monster 800 has a metal tank, its FI and it has a rust problem.

About 12 months ago I took the tank off, got rust cut out and the tank painted and then sealed the inside. However the job must have not been the best as Im weeping fuel now.

Basically I want to replace the tank but am having a hell of a time finding a replacement.

Due to my bike being the 800 of 2004 am I restricted to only that model of tank?

Will a 620 tank fit it?

Currently Im scouring eBay but are there any other places I should be looking?

Metal or plastic doesn't worry me I just want the damn thing to fit and not leak.

Cheers

Phil

Gday Phil and welcome.
Post this question in the Tech section and you'll get more hits.
Good luck.

@tshearman

I'm not sure if the bottom shape will clear the battery, coil and ignition equipment on your '99 M750.
If it does.....
Then, likely you would need to remove all of the pump and pressure regulator hardware from the inside.
Then select which fuel passage to use, plug the other one, and get one of the OEM plastic quick disconnects from the plastic-tank bikes.
And fit a fuel filter.



@Thephil

'01 and '02 S4, and steel S4R tanks will fit, but will have slightly reduced capacity due to the shape of the bottom.

'02-'05 M620, M750, M800, M900, and M1000 tanks will be the same as what you have.

Plastic tank will fit, and if it comes with all of the pump apparatus inside, you're good.
You would need the mating OEM quick-disconnect fittings that came on the bikes with plastic tanks, and the hinge plate.
You would need to eliminate the fuel pressure regulator that's on your throttle body, as the plastic tanks have it inside.

Yes, do move this post to Tech.  As long as the pump and filter come out the top any metal FI tank should fit.
