Thread: Fuel Pump Connection

  1. #1

    Default Fuel Pump Connection

    I have a proper fuel pump wiring existing in my car (fuel pump, 30A relay, 20A fuse, fuel pump simply operates with ignition ON constantly). Now installing a Holley HP EFI the question will be, is there any disadvantage NOT to use the green (loose) wire to control the fuel pump or can I leave the installation as it is? Cheers, Martin

    You can leave it as is, but there's a significant safety benefit to an ECU controlled fuel pump (it only runs when an RPM signal is present).
    May God's grace bless you in the Lord Jesus Christ.

    Danny, many thanks. I'm not finished with wiring, one additional cable is not a big issue for my own safety. :-)
