So today I was checking the fuel pressure on the 93 2.3 and at first every thing was good. It showed 40 psi with key on/engine off. However with the engine on pressure drops almost out of tolerance down to 30 psi. This is where it gets interesting because when I unplug the vacuum source from the fuel pressure regulator pressure jumps to 40 psi and holds it even when reving the motor. To me 30 psi seems very low with a newer flue pump and new flue filter.
