Radium Fuel Rail - BMW E46 M3 S54 (Rail Only)

Application: BMW S54 engine – E46 M3, Z3 M Coupe/Roadster, Z4 M Coupe/Roadster Part Type: Upgrade fuel rail (fittings sold separately) Part Number: 20-0070-02

This Radium fuel rail is machined and anodised for use with all fuel types including E85. Its large 0.65in internal bore supports all necessary engine power requirements, and it is a direct bolt-on for BMWs with the S54 engine.

The end ports are tapped for 8AN ORB adapter fittings, which can be used in either end. If the under-car regulator is not used, a Radium direct mount regulator can be fitted in the front port. The centre port is tapped for 3/8" NPT adapter fittings and can be plugged if unused, making this rail ideal for custom high-flow fuel system builds.
