Product images may differ from actual product appearance.

Made of billet aluminum with an anodized finish, the 4-Port PLUS+ is designed for high-volume, gasoline-only applications and offers excellent flow ratings. This regulator can maintain constant pressure settings while meeting the demands of today's fuel systems. You'll see the 4-Port PLUS+ on many NHRA Pro Stock 500ci engines using two Holley Dominators. It is ideal for high-horsepower single four, tunnel ram, or other multi-carburetor application using gasoline and is adjustable from 5 to 15 psi with a lifetime labor warranty.
