recommened fuel pressure I had a previous thread about fuel pressure for my stock LM7 5.3l
not sure if it was posted here or in fuel section,
but anyways my issue was i only had about 45 psi at idle. 54 at WOT or vacuum line disconnected (fuel rail FPR)
So after my high pressure fuel blowing up my Fuel pressure regulator two times because of my return line being restricted. i went out and bought a o reily auto parts brand regulator.
I never did see my fuel pressure before i bought this regulator so i had no comparison to my previous.
well come to find out, i put a original GM 6.0l regulator to test it, had 54 at idle like i should.
the schucks brand must have been bypassing fuel, because it was so low on pressure
the whole message im trying to set here, is if you purchase one of the auto parts store regulators it might give you the same issue.
