Holley Fuel Pressure Regulator, 1 to 4 psi Adjustable

Click for a larger picture of Holley Fuel Pressure Regulator, 1 to 4 psi Adjustable

Holley makes the best low-pressure fuel pressure regulators we have found. It helps to ensure a constant, steady flow of gas to the carburetor regardless of variations in fuel pump output pressure.

The 1-4 psi model is preset to approximately 2.7 psi. With the aid of an accurate pressure gauge, it can be easily adjusted as required within its specified range.

There is one inlet port (bottom) and two output ports (side) to aid the connection of multiple carbs. Alternately, single carburetor applications can use the remaining port for a fuel pressure gauge. All of the ports are 3/8 NPT female.

Comments about Holley Fuel Pressure Regulator, 1 to 4 psi Adjustable:

I trust Holley products. Chromed finish and smooth surface may a nice looking object. Operation with a 60 hp engine is as it should be. I have two, and their regulated output as set from the factory is very close to the 2.7 psi listed. They match within about 1/4 psi. Mine are used in a high vibration environment, so shock mounted, as a precaution. Only complaint, is I wanted to readjust mine, and haven't been able to loosen the adjustment screw and jam nut on either regulator. They may be locked with red thread locker. If you may ever want to adjust yours, loosen the adjuster before any shock mounting.

Service and delivery comments:

My fuel pressure regulators were in stock and delivered to the Madison area the next day, even though I hadn't placed the order before 5 pm! They were well packed and arrived in perfect condition.
