Radium Engineering Secondary Fuel Rail

The fuel rail ports are tapped for 8AN ORB

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

This Radium Engineering secondary fuel rail is for aftermarket 6-port intake manifolds that are produced for the Mazda 20B-REW rotary engine. 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 compatible with these fittings. The extra center port (shown above) allows additional fuel system accessories such as the OEM fuel temperature sensor (shown below using 14-0421), a pressure transducer, Radium fuel pulse damper, etc.

nsulating phenolic spacers and washers are included with stainless steel hardware to prevent thermal energy from conducting heat into the fuel. The two M8 extension mounts are made from stainless steel for superior strength and corrosion resistance.
