Radium Top Feed Conversion Fuel Rail, Mazda 26B Primary

Application: Mazda 26B 4-rotor - primary injectors
Part Type: Top feed conversion primary fuel rail
Part Number: 20-1126


The Radium Engineering 20-1126 is a high-flow primary fuel rail for the Mazda 26B 4-rotor engine. Thermal insulating spacers and washers are supplied with stainless steel hardware to stop heat from the engine conducting into the fuel.

The included 14mm lower injector seats were designed to work with or without the OEM diffusers in place, and their FKM O-rings make them suitable for boosted applications. The green injector seats extend the O-ring past the air-assist injector holes in the iron. The rail has four 8AN ORB ports - the extra centre ports allow accessories such as the OEM fuel temperature sensor (using 14-0421), a pressure transducer or a Radium fuel pulse damper.
