    Fuel Pump Rebuild Kit Type
    Sold as a kit
    Manufacturer's Part Number:

    Looking for a fuel pump that is quiet, stylish, powerful, and dependable? Then look at the Holley HP 125 and HP 150 series fuel pumps. The exclusive gerotor gear set quietly and efficiently pumps the fuel without the noise of traditional vane pumps. The chrome plated steel motor and trick powder coated bracket match the mil-spec hard anodized aluminum base for unsurpassed beauty and durability. While these Holley pumps have the capability to feed stout race engines, they are equally at home on the street due to their design and construction.

    The Holley HP 125 delivers 125 GPH of fuel at free flow (110 GPH at 7PSI) and is internally regulated to 7 psi to eliminate a separate regulator on most carbureted applications.

    The Holley HP 150 delivers 150 GPH at free flow (140 at 7 psi) and is internally regulated at 16 psi to work efficiently with the included 4-7 psi regulator (Holley P/N 510-12-803)
