    Default Fuel Pressure

    I just picked up a Holley 550-200 2V Avenger EFI system. It's rated at 275 HP running 21 lbs fuel pressure. My question is, what's the max fuel pressure these injectors can safely handle?

    The fuel pressure can be raised to 43 psi on the Delphi TBI injectors (not so with the older B2 injectors).
    Although, the TBI fuel pressure regulator (spring) will reach its maximum (bottom-out) around 26 psi.
    Of course, you can abandon the TBI fuel pressure regulator, and use a remote fuel pressure regulator.

    May God's grace bless you in the Lord Jesus Christ.
