Universal Adjstable Fuel Pressure Regulator Black

The AEM Electronics Universal Adjustable Fuel Pressure Regulator Black (model 25-302BK) is a precision fuel management component designed for engine builders, performance tuners, and enthusiasts who demand reliable fuel delivery across varying engine loads and RPM ranges. This regulator is essential for maintaining consistent fuel pressure to your injectors, preventing lean conditions under boost or wide-open throttle scenarios.

AEM's design features a sealed diaphragm construction that isolates the regulator spring from fuel contamination, ensuring long-term durability and repeatability. The fully adjustable regulator allows you to set base fuel pressure from approximately 30 to 90 PSI, with vacuum-referenced compensation that automatically adjusts rail pressure in relation to manifold vacuum. This feature helps maintain proper fuel mixture during part-throttle cruising and hard acceleration, enhancing fuel economy and reducing emissions.

This fuel pressure regulator is ideal for naturally aspirated builds seeking improved throttle response, turbocharged applications requiring stable rail pressure, and fuel-injected conversions on classic vehicles. Its compact black aluminum body measures 4.35 x 3.35 x 4.7 inches and weighs just 0.71 lbs, making it suitable for various installations.
