Radium Top Feed Conversion Fuel Rail, Mazda 26B Primary

The Radium Engineering 20-1126 Top Feed Conversion Fuel Rail is designed for: Mazda 26B 4-rotor — primary injectors.

The Radium Engineering high flow primary fuel rail is for a Mazda 26B 4-rotor engine. 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 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. The new green injector seats were designed to extend the O-ring past the air assist injector holes in the iron.

The fuel rail has four ports that are tapped for 8AN ORB fittings. 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.

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. Dimensional drawings are available from Coore on request to verify clearance.
