Holley HP Billet Fuel Pressure Regulators

Part of Holley's complete line of fuel system products, Holley HP billet fuel pressure regulators are available in a variety of configurations for carbureted or fuel injected engines. Some versions are even adaptable to either carburetors or EFI. They allow you to upgrade a carbureted system to EFI without replacing the fuel pressure regulator.

All HP billet fuel pressure regulators feature a 2-port design, provide for precise fuel pressure adjustments, and are available in your choice of demand (no return line) or by-pass (with a return line) styles. Depending on the model, they are for use only with electric fuel pumps, or with either mechanical or electric pumps. Designed for street/strip applications, they are CNC-machined from 6061 T-6 billet aluminum for strength and have bright dip anodized black bodies with clear dip anodized tops for corrosion resistance and good looks. Whatever your fuel system needs, Holley has you covered.

Depending on model, features may include:

* Adjustable from 4 to 65 psi for use with EFI or carburetors
* 4.5 to 9 psi adjustment range for use with carburetors only
* EFI-only models are adjustable from 15 to 65 psi
* Two port sizes available, 3/8 in. NPT or -6 AN inlet/outlet and return (where applicable)
* Fitting for manifold reference
* 1/8 in. NPT gauge port
* Boost reference--1:1
