Adjustable Billet By-Pass Regulator 3/8 NPT Kit
Adjustable billet by-pass return style fuel pressure regulator 3/8 NPT Kit with Fuel Pressure Gauge and Adapter Fittings Boost Reference - 1:1
Holley Billet Fuel Pressure Regulators are part of a complete line of fuel system products from Holley. They are precision machined from 6061-T6 billet aluminum for strength and durability. These regulators are adjustable from 4-65 psi and will handle both carbureted and EFI applications. A second pressure spring is included allowing you to increase the fuel pressure range up to 65 psi for EFI systems. They have 3/8 NPT port sizes to adapt to your new or existing fuel lines. So, if you are currently running a carbureted system but plan to upgrade to EFI in the future, these regulators will have you covered either way. These kits include a fuel pressure gauge and adapter fittings to get you started on your installation.
