Aeroflow fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburettor. 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 aluminium regulators are fully adjustable from 1 to 11 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 dead head system with no return line. Available in blue, black and red anodised or polished finishes. Suitable for use with pump fuel, E85 alcohol and diesel fuels.

Note: Recommended for use with Carburettor fuel pumps only - not EFI.
