Modest beginnings of my M750 project

[Duck-Stew]

As I have mentioned I am switching to an ss tank. It was listed as a 96/97. Anyone know if the filler cap from my 99 monster tank will fit the ss? Its coming without the entire cap, just a big ass hole.
If not maybe I will get one of those keyless racing caps...

Monster fuel cap will fit into the fuel cap flange that goes into the SS tank.  Seems like you'll need a fuel cap flange.  (This is used to allow enough room to get one's arm into the tank to install the OE electric fuel pump which is low-pressure on the 91-98 SS bikes, and high pressure on the injected Monsters and SS bikes.)

Since your bike is a '99, you *may* need to install the OE low-pressure fuel pump but maybe not.  Depends on the position of the fuel petcock and the float bowls of the carbs.  If sufficient height difference is there, you could just get away with a gravity fill of the float bowls.

Thanks DS. I started a gas cap thread here http://www.ducatimonsterforum.org/index.php?topic=62273.0

Will the stock monster fuel pump be insufficient? The plan is to run the line out to a manual shutoff >inline filter>stock pump>FCR's.

[Duck-Stew]

Stock pump will suffice. Just plumb the supply to the pump from the return port so as to pull from the lowest point in the tank.

Your proposed routing is fine.

the return line in a carby ss tank is a tube that goes up to the front of the tank from memory.  i think you'll need an in tank pump or to cut the in tank tubes at the base of the tank.

Brad's memory is pretty good.

I dont get it but once its here and im looking at it im sure it will make better sense. (or a diagram perhaps?) Thank you

I was thinking of the injected SS tanks which return fuel directly to the floor of the tank (which makes them a great supply port).  Brad's right (as per usual).  The Carbed SS tanks have a return pipe which runs up to the front of the tank near the roof making them a poor supply port for a gravity fuel feed...

Understood. So I can run the standard fuel out to an external pump like on the monster? Im getting confused (as per usual).
Or, as stated, do I gotta get in there and cut down the metal tube?

You'll need to either cut the tube, or run an internal low pressure pump.

The fact that the ss tank incorporates a return allows you to run a pump with a bit more pressure without as much concern  regarding overcoming the needles.

Ok. So for an aftermarket solution, what psi are we talking for an internal pump?

Something like this would be ideal, but it isn't very affordable... https://www.pegasusautoracing.com/productdetails.asp?RecID=6551

I'm not sure how much pressure the SS pumps ran. I'll try to find out.

You'll also need a sender with a feed for the pump if you go internal.

You should wait to get the tank and look before you decide which route you're going to take.

True. The sending unit might be in there still. Didnt ask. Seems like the internal route is more complicated but cleaner looking. Yes, when the tank gets here I will asses what to do.
On another note someone was asking about my dash area. So here are some pics of that cobbled arrangement. I plan to make a nicer bracket when time allows...The little light is for fuel level.

Ingenuitive however i MUST ask.  Is that indicator light being held on with a ground rod clamp??

You got it. Nice gold color. Simple application. I love the neat bits one can find at Home Depot.
