Thread: Dominator Fuel Pump & Regulator

  1. #1

    Default Dominator Fuel Pump & Regulator

    Starting a new project. It will start out as a blow thru carb (turbocharged), later switch to EFI.
    Looking at the Dominator 12-1400 fuel pump and 12-847 regulator (carb).
    Can the regulator be changed over with a spring to EFI, or does the 12-848 (EFI) need to be used?

    You'll have to call Holley Tech about that. I don't know if they'll sell you just the spring, or if the internal orifices are the same.
    May God's grace bless you in the Lord Jesus Christ.
