The Radium Engineering high flow primary fuel rail is for the 20B-REW rotary engine originally found in the 1990-1995 Mazda/Eunos Cosmo. The aluminum fuel rail is anodized black for compatibility with all popular fuel types including E85. Manufactured with a large internal bore, the fuel rail can support all necessary engine power requirements.
The three 8AN ORB ports are featured on this fuel rail. The extra center port allows additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421 shown below), a pressure transducer, Radium fuel pulse damper, etc.
Insulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The included 14mm lower injector seats were designed specifically to be compatible with or without the OEM diffusers in place. They feature Viton O-rings making them suitable for boosted applications.
