Radium Engineering Top Feed Conversion Fuel Rail - Mazda 26B 4-Rotor - Primary
Radium Engineering's high-flow primary fuel rail converts the Mazda 26B four-rotor to top-feed injectors. Thermal insulating spacers and washers are supplied with stainless hardware to limit heat soak into the fuel (SKU 20-1126).
The 14mm lower injector seats work with or without the OEM diffusers and use FKM O-rings suitable for boosted engines; the green seats extend the O-ring past the air-assist injector holes in the iron. The rail has four 8AN ORB ports, with the extra centre ports available for accessories such as the OEM fuel temperature sensor (via Radium 14-0421), a pressure transducer or a Radium fuel pulse damper.
Note: Port fittings are sold separately and must suit your application. Allow clearance around the ports for larger accessories such as regulators, gauges and pulse dampers. Installation by a professional is recommended.
