From AEM:

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. A longer spring provides for a wider range of adjustment (from 40 to 130 PSI). An easy-to-adjust set screw stands up to repeated adjustments.

A single large return orifice is designed to handle high rate flow pumps. The regulator has a 1:1 rising pressure rate for boosted applications, and it is alcohol fuel and race fuel compatible. 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.
