Radium Engineering Secondary Fuel Rail

he fuel rail has four ports that 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.

The Radium Engineering high flow primary fuel rail is for a Mazda 26B 4-rotor 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 extra center ports allow additional fuel system accessories such as the OEM fuel temperature sensor (using 14-0421), a pressure transducer, Radium fuel pulse damper etc.

Thermal insulating 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 (shown above) were designed specifically to be compatible with or without the OEM diffusers in place. They feature FKM O-rings making them suitable for boosted applications.
