WHAT IS THE CORRECT FUEL PRESSURE SPECIFICATION?

1987 Oldsmobile Delta 88 • 86,000 miles

I have 30 psi after the fuel pump before the filter and 30 psi at the test port on the engine after the pressure regulator. Do I need a pump or a regulator?

41-47 psi is correct pressure if port fuel and 9-11 if tbi.
