Holley 12-803 REG, FUEL PRESSURE 4.5-9 PSI M/P

Holley Fuel Pressure Regulator 4.5–9 PSI

SKU: HOL12-803

This fuel pressure regulator is designed for carbureted gasoline engines and features a 3/8-inch NPT inlet and outlet. It offers a 4.5–9.0 PSI range, includes a non-return two‑port design, and comes in a shiny finish.

Holley fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. Too much fuel pressure for a given needle and seat assembly can overload the needle and seat and may cause flooding or drivability problems. Each Holley fuel pressure regulator is fully adjustable, so regulating the fuel pressure to your engine's needs is a simple task. All Holley regulators are pre-set at the factory, so there is no guesswork when first installing the regulator.
