Fuel pressure…. The book…. KOEO 35-45. KOER 30-40.
original fuel pump 136k miles, 3psi KOEO 26-28 KOER
Suspect fuel pump or pressure regulator weakening…
new fuel pump by Precision installed- KOEO initial burst 36, rests at 32 psi koeo. KOER 26 idling, 36 with pressure reg unplugged from vacuum.
new fuel pressure regulator KOER 28.5-29 psi, 38 psi with vacuum unplugged.
those small differences make a big difference in driveability. Damn truck!
4 psi makes a difference. Putting the bed back on and taking a test drive here in a couple minutes.
