dapiper Posted July 17, 2007 Share Posted July 17, 2007 My fuel press will not stay put. Thought it was set at 40 psi, but at 45 so lowered it. Then low at 35 after running. Incr to 40 and next day 45 when cold. What gives? Using Bosche pump which needs repl since just discovered flow is off 20%. Anyone have a -044? Also using Aeromotive reg, fuel rail and RC 550 inj.
