Fuel Pressure Drops? What could it be?
After upgrading my fuel system, I've been noticing a problem with the fuel pressure dropping after driving the car.
Fuel Setup:
- Aeromotive 1000 Fuel Pump
- -10an Steel Braided Feed Line
- -6an Return Line
- x2 inline filters (1 before the pump) (1 before the fuel rail)
- Aem Fuel Rail
- Aeromotive Bypass FPR
I made sure the bolt on top of the FPR is not moving, but the fuel pressure seems to be dropping anywhere from 10 to 20psi, depending how long I drive the car before checking it and raising it again on the FPR.
Anyone have an idea what the problem could be?
Thank.

it can either be the pump or the FPR. if it keeps dropping after u drive it then its the FPR. did u sump ur tank? change the fpr and check to see if it solves the problem

Vacuum lines have been checked and there is no leaks. Yeah the tank has been sumped.
