Compatible with alcohol/race fuels and adjustable from 40–130 PSI, the 25-305BK from AEM is the ideal choice for racers who need reliable fuel pressure in high-boost vehicles and race cars that require a large volume of fuel delivery.
An easy-to-adjust set screw easily endures repeated adjustments, while one large return orifice is up to the task of handling high–rate flow pumps. This universal fuel pressure regulator additionally has a 1:1 rising pressure rate for boosted applications and is tapped to accept 9/16”-18 O-rings for inlet and return. AEM included a 1/8 NPT port for compatibility with a pressure sensor pick-up or fuel pressure gauge.
