Probably going to need to run an adjustable FPR to get the flow down to a managable level...

The siphon hole will likely need to be drilled out as well.

Back from the dead...

So it seems a 255LPH Walboro with a Rewire would handle a ton of power before going with a crazy fuel system upgrade. My goal is to retain the stock Rail/FPR on by BB FP Red.

I think it could handle whatever power level were possible for pump gas, but it's only good for at best about 500 whp on E85 without a boost-a-pump.
