This Radium Fuel Pressure Regulator (FPR) is built around an OEM Bosch regulator top. These billet 6061 aluminum adapter fittings allow an OEM fuel pressure regulator to be reused in an application other than the OEM fuel rail. It features 3/8" NPT male threads with a bright dipped Type-II anodized surface finish. Each end of the adapter mimics the profile of an 11/16" (18mm) spanner for rotating during installation.
