AEM Adjustable Fuel Pressure Regulator Rebuild Kit - Restore the performance of your high-mileage fuel pressure regulator with AEM Electronics fuel pressure regulator rebuild kits. You'll regain the accuracy and performance that your regulator had when it was new.

The AEM adjustable regulator is CNC machined from 6061 T-6 aluminum. The fuel outlet port is tapped to 9/16-18 threads, which allows the use of several different hoses up to –8 AN hose. The vacuum reference is 1:1 ratio so for every pound of boost on a turbocharged or supercharged application yields a 1-pound rise in fuel pressure. The range of adjustability is from 20 PSI to the maximum the fuel pump can deliver.

Note: There are two different styles of AEM adjustable fuel pressure regulator diaphragm/orifice sets- a flat seat and a ball seat. Parts from the two different styles are not interchangeable. When replacing an old diaphragm with a new one from this rebuild kit, the fuel return orifice MUST be changed to the ball seat style (included in this rebuild kit) if your regulator is not already so equipped.
