Whether you're simply upgrading injectors on your stock injectors in your Cosmo or carrying out an engine conversion into an early model car, this Radium Engineering 20B Primary Fuel Rail Kit will help you get the job done neatly and most importantly, correctly.
This high-flow primary fuel rail has been designed for the 20B rotary engine with a large internal bore to support both stock & high-horsepower applications. Each rail is CNC machined from billet 6061 aluminium and anodized black for sleek looks and full compatibility with all popular fuel types including ethanol E85.
Each rail features three 8AN ORB ports off the shelf, with the extra center port supporting additional fuel system accessories such as the OEM fuel temperature sensor or an aftermarket pressure sensor with the use of an adaptor sold separately (see extras tab). If not required it can simply be blocked with the supplied in-hex blanking plug.
Included with each kit are a pair of insulating phenolic spacers and washers with stainless steel hardware as well as two 14mm lower injector seats that are compatible for use with or without the OEM diffusers in place.
