Performance Benefits
Holley fuel pressure regulators are engineered to precisely control fuel pressure from the fuel pump to the carburetor. Proper fuel pressure regulation prevents needle and seat overload, which can cause flooding or drivability problems. The fully adjustable design allows you to dial in the exact fuel pressure requirements for your specific engine and carburetor combination.
