AEM (25-305BK): High-Capacity Universal Adjustable Fuel Pressure Regulator

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.
