AEM's High Cap Universal Adjustable Fuel Pressure Regulator (PN 25-305BK) is the perfect solution for racers who need reliable fuel pressure in high-boost vehicles and racecars that require a large volume of fuel delivery.

The High Cap Universal FPR is tapped to accept a 9/16”-18 O-Ring sealed fittings for inlet and return, and includes a 1/8 NPT port for a fuel pressure gauge or pressure sensor pick up.
