This Radium Engineering fuel rail is a direct bolt-on with all twin cam engines. Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. The Radium fuel rail converts the OEM side feed fuel injector setup to top feed allowing the use of high flow 14mm O-ring fuel injectors (not included). This kit is compatible with E85. The rail is CNC machined from solid 6061 aluminum and black anodized for a high quality surface finish. If planning to use with an Xcessive intake manifold, please note that the fuel rail may need to be shimmed to the proper height, depending on fuel injectors used. Also, the aluminum injector seats included in this fuel rail kit will not be used.
