can anyone tell me where the vacuum line is on our stock FPR? i have something interesting i wanna try but not sure if we have a vacuum on the factory FPR , do we?
The wire is a ground.No vac/boost lines are used at all. 58PSI both vac. and full boost.fg2srt4 said:no vacuum line on FPR because its a static system, meaning that you get the same fuel pressure all the time. the fpr is on top of the pump on the bottom side of the gas tank its got one feed line and a signal wire of some sort attached o it.
