AEM High Cap Universal Adjustable Fuel Pressure Regulator (PN 25-305BK) is designed for high-performance applications such as racing vehicles. It offers a wider adjustment range (40-130 psi) compared to standard regulators due to its extended spring. The regulator features a durable set screw for frequent adjustments and a large return orifice to accommodate high-flow fuel pumps. It maintains a 1:1 rising pressure rate in boosted applications and is compatible with alcohol and racing fuels. The regulator accepts 9/16"-18 O-ring sealed fittings for inlet and outlet and includes a 1/8 NPT port for a fuel pressure gauge or sensor.
