Any EFI experts out there? Fuel problem...

[mtm_seven]

I added an extension to the return line and had moderate success but I still think that since my return line I.D. is smaller than the inlet that gravity feed just can't keep up with the flow - basically, unless I add a low pressure pump upstream to feed the high pressure pump then I'm looking at a fuel starvation issue every time I get below half a tank. Problem with that solution is a low pressure pump can't keep up the same volume.... starvation again.

My pocketbook is trembling at the thought of dropping $700+ on a custom tank with internal pump but that looks like the only dependable solution.

I hate that I spent so much time and money trying to rig the stock tank to work.
