Description

Aeroflow bypass fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. Too much fuel pressure for a given needle and seat assembly can overload the needle and seat and may cause flooding or drivability problems. These billet aluminum regulators are fully adjustable from 4.5 to 9 PSI so regulating the fuel pressure to your engines needs is a simple task. available with either 3/8″ NPT or -8ORB female threads and are the perfect choice for fuel systems running a return line to the tank with added benefit of less load on the fuel pump resulting in quieter fuel pump operation, cooler fuel and improved fuel pump life. Available in blue, black and red anodized or polished finishes.

Suitable for use with pump fuel, E85 alcohol and diesel fuels.
Note: Recommended for use with Carburetor fuel pumps only – not EFI.
