Holley HP Fuel Pump 12-600 | Looking for a fuel pump that is quiet, stylist, powerful and dependable? Look at the new Holley HP 125 and HP 150 series fuel pumps. The exclusive gerotor gearset quietly and efficiently pumps the fuel without the noise of traditional vane pumps. The chrome motor and trick powder coated bracket match the mil-spec hard anodized base for unmatched beauty and durability. While these pumps have the capability to feed stout race engines, they are equally at home on the street due to their design and construction techniques.
