The AEM High Capacity Universal Adjustable Fuel Pressure Regulator (PN 25-305BK) is designed for high-performance racing applications where reliable fuel delivery and precise pressure regulation are critical. Crafted from CNC-machined 6061-T6 billet aluminum and finished with a durable black anodized coating, this regulator offers exceptional durability and corrosion resistance. Its versatile design features three -6AN (9/16-18) ORB O-ring style inlet ports, including two inlets and one return, making it adaptable to a wide range of vehicles and fuel systems. The high-capacity construction supports large volume fuel demands, making it ideal for high-boost turbocharged or supercharged engines that require a consistent fuel supply at various boost levels. The integrated 1/8" NPT gauge port allows easy installation of pressure sensors or gauges to monitor fuel pressure accurately in real time. The regulator's longer spring provides a broad adjustment range from 40 to 130 PSI, accommodating various tuning requirements, while the boost-dependent rising fuel pressure rate (1:1) ensures optimal performance under boost conditions. The inclusion of a universal mounting bracket and four 10-32x1/2" screws simplifies installation. Please note that Barb fittings for outlet ports are sold separately (PN 25-390). This regulator is compatible with alcohol fuels and race gas, making it suitable for demanding racing environments. It is not CARB approved and requires acknowledgment of this status prior to installation. The high-capacity design and adjustable features make the AEM PN 25-305BK an excellent choice for racers seeking precise, reliable fuel pressure regulation in high-performance setups.
