All about fuel tanks!

[ducpainter]

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!

[Speeddog]

Are you using carburetors or FI?

[Rudemouthsky]

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

[Speeddog]

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

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
