'95 7.3 Low fuel pressure at idle....
Recently joined. I have been a member of another site for a couple of years. I have had my truck now for a couple of years and have been making upgrades and repairs every since. I installed a new lift pump to correct what I thought was a lack of power. Since then I have discovered that Ford actually put 3.54 gears in a 1 ton 4x4 Dually! Anyway new lift pump installed, new fuel filter, new spring in the fuel pressure regulator, and all I can get is 50 psi at idle. Haven't check it with a load yet, hopefully tonight. Gauge is a autometer liquid filled gauge. Anyone had similiar results with a new pump? The more I learn the less I know!! Thanks.
