This weekend I jest look at my fuel leak when I was going into highway, it was my old fuel return line that I forgot about and was leaking fuel to the ground since it was not connected cause of the return line of the sfmu. Right now im running... tank, feed line, fuel filter, oem fpr, rail, sfmu at 22 psi (440CC), fp gauge, fuel return line, tank. That seem to work but in logic I didnt get 22psi at the rail right ? since Ive keep the oem fpr it raise it again to 48psi or dont remember... and then lower it to 22 after the rail right ? Can I keep the oem and the sfmu ? Oh and for nom ive just put a bolt into the old fuel return line and clamp it.

Shouldn't it be tank-feed line-fuel filter-oem fpr-rail-*fp gauge*-sfmu-fuel return line-tank? That's how mines hooked up. Plug the old return line from the oem fpr and the vacuum line also.

Mine is after the sfmu but I dont think it matter if you have only 1 fpr. But in my case, ive kept the old one and I think the old one raise my pressure to stock and after the sfmu lower it. I cant run the 2 return lines to the tank. On and since ive block the old one, the car dont pull... its slow and ugly rich. Idle is ok but anyuthing else is just RICH.

dude, you should just pull off the stock fpr and put the sfmu in its place the same way the stock one is. then its simple instructions and no guessing from there.
