If you're looking for an easier & neater way to run some additional injectors on your 3-rotor when switching to E85, this Radium Engineering 20B Primary & Secondary Fuel Rail Set will help you get the job done neatly and most importantly, correctly.

This high-flow fuel rail set has been designed for the Cosmo 20B triple rotor engines with a large internal bore to support high-horsepower applications and supplies you with everything you need to set up with your chosen injectors and go. 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.


While the primary rail supports 3 injectors as per standard, the secondary rail features 6 injector ports and is compatible for use with the popular 6-injector Xcessive Manufacturing 20B lower intakes which are a common upgrade on big power 3-rotors running E85 and alcohol-based fuels.

Each rail features three 8AN ORB ports off the shelf, with the extra centre port supporting additional fuel system accessories such as the OEM fuel temperature sensor, or an aftermarket fuel pressure sensor with the use of an adaptor which is available separately (see extras tab) If not required it can simply be blocked with the supplied in-hex blanking plugs.

Complete packages with fittings, Injectors & more coming soon.
