Is 58 psi good enough for a vortec 305 when the engine is idling, key on engine off starts at 35 psi and when I cycle it again it slowly builds up pressure is this normal?
IF (big IF) the pressure isn't improved by the fresh fuel filter, you'd better verify the power supply to the pump. A pump starving for electrical power could have low pressure, or build pressure slowly.
But that's not the only potential cause of low 'n' slow pressure.
