    Corvette fuel filter , 6.0l and fuel pressure ?

    The truck runs very well right now but its just something ive been thinking of lately.

    The motor is an 06 lq9, and i used the corvette fuel filter/reg seeing as the fuel rail system on the motor was returnless. The injector info im using is for the 06 6.0L .. but is the regulator im using providing the proper pressure or is it actually too high ?

    Should be 55-60psi. Ideally 58psi.

    Only way to know for sure is to put a gauge on it.
    I have a vette regulator on my setup and it is dead nuts on 58.

    The stock fuel pumps are set at 58psi, at least for the C6.

    He is talking about the C5 regulator/filter assembly.

    Mine reads 58 with that regulator/filter. By the way, the pump is actually over 100 psi, that's why the regulator is there to control the pressure to 58 psi or so.
