Tank Modifications....

[latemarch]

Because I have a fuel injected engine I am going to need a fuel return inlet in the tank system somewhere. Since that requires some welding I was thinking of changing the diameter of the fuel outlet lines to a larger (say 1cm) to provide for a large flow volume between the tanks.

It would allow the return line from the fuel rail to only go to one tank (the right) and would allow me to fuel the Tr1ke from either side instead of having to fill both tanks.

Anyone see any issues before I start cutting and welding?

You can drill a hole in one of the fuel caps for breathing and use the original breather inlet for fuel return?

I like that idea, that makes good sense :-)

That puts all the fuel in one tank unless there is sufficient cross flow. Which brings me back to making a larger cross pipe and back to welding on the tank.

Good point, never thought about that


In relation to what is being used, how much fuel comes back up the line?

I remember having to plumb in a return on my MNR, but it used one tank. I just wonder if you would have an issue just plumbing it back to one tank?

Can't be too hard to fabricate up an alloy y piece, or just buy a cheaper alternative plastic y piece, I have lots spare, but im sure you can source them easy enough.

I made a extra 1" connection between the two tanks. But for me it's easy because I have stainless steel tanks. And yes, I am aware I must make a heat shielding between the hose and the exhaust .
Also, make sure both tanks can breathe (so no vacuum can be created)
