Description

The Radium Engineering fuel rail is a top-feed conversion for the Mazda 20B-REW rotary engine. Constructed from anodized black aluminum, it is compatible with all popular fuel types, including E85. The rail features a large internal bore to support high engine power requirements and includes three 8AN ORB ports for additional fuel system accessories. Insulating phenolic spacers and stainless steel hardware are provided to minimize heat transfer to the fuel, and the 14mm lower injector seats are designed for use with or without OEM diffusers and feature Viton O-rings for boosted applications.
