Show original supplier description
The AEM Universal Black Adjustable Fuel Pressure Regulator (25-302BK) offers a versatile solution for managing fuel pressure in a wide range of vehicles. Engineered to support engines up to 1,000 horsepower, this regulator allows for fine-tuning from 20 psi to the maximum capacity of your fuel pump. Its construction features a boost-dependent rising fuel pressure rate, maintaining a precise 1:1 ratio. Crafted from durable 6061-T6 billet aluminum, the regulator is designed for longevity and performance. It includes a 1/8 NPT port for the installation of a fuel pressure gauge or sensor, and is tapped to accept -6 AN or 9/16"x18 fittings. The product is also noted as not being CARB legal and not for sale in California. This is a universal product, meaning it does not come with specific fitment application data. Buyers are advised to manually verify compatibility with their vehicle's fuel system. Compatibility information for specific models such as the 1986-1993 Acura Integra, 1988-1991 Honda Civic, and 1991-2001 Honda NSX has been noted for related but distinct part numbers, underscoring the need for careful individual verification for the 25-302BK.
