Holley Releases Diecast Bypass Fuel Pressure Regulators
06/12/2017 < Back to Blog Home
If you’re running an electric fuel pump, chances are you’re going to need a regulator to control fuel pressure. Available in polished chrome or black e-coat, Holley Die Cast Return-Style Fuel Pressure Regulators are available for both carbureted and EFI applications. The carbureted regulators come preset from the factory at 6 PSI; EFI fuel regulators are preset to 60 PSI. Although the pressure is preset from the factory, you can easily readjust it to meet your specific requirements by loosening the locknut and turning the screw clockwise to increase the pressure or counterclockwise to decrease it.
Holley Die Cast Return-Style Fuel Pressure Regulators also have an optional boost-reference fitting. Just remove the vent plug in the regulator cap and replace it with the supplied barb fitting. The regulators feature 3/8” NPT inlet, outlet and return ports – a 1/8” NPT gauge port is also available. For easy fuel pressure adjustments, use one of Holley's mechanical fuel pressure gauges, which are available at price point affordable for virtually any budget. Installation is a snap – just follow the detailed, step-by-step instructions.
