so you kept the internal pump? because otherwise you have to have some way to get the fuel from the bottom of the tank right? or is that part of the sump itself? i thought the sump was just a way to keep fuel near the pump, i guess maybe im getting my info screwed up lol

Its part of the sump itself, you have a fitting on the end of the sump (which is at the lowest point of the tank) so the fuel is always able to get pulled from the tank to the external pump.

that makes sense. So one more question, is it easy to keep stock rails and just add a regulator at the beginning of the rail and keep the fprs to that the computer is all happy? or do i need different rails? also if i do that and run 40 psi rail and keep the fprs hooked up, would i disconnect the fpdm? and would the computer take that in stride so i wouldnt need a retune? cuz im leaning towards this if i dont need to retune for now, because he left me rich so im thinking if i can get fuel supply figured out i can cuz size down a pullie to pick up some of the lost power pretty safe.
