This big bore fuel rail is machined, polished, laser etched and then anodized for a stealth surface finish. It is compatible with OEM and aftermarket direct fitment fuel injectors. It features a large 0.65" internal bore with -8AN ORB (3/4-16 O-ring) threaded ports at each end and 3/8" NPT female centre port to accept a variety of adapter fittings for custom high flow fuel system builds. It is compatible with all fuel types including popular alcohol mixtures such as E85. The fuel rail is a direct bolt-on for all BMW's equipped with the S54 engine, including:

2001-2006 BMW M3
2001-2002 BMW Z3 M Coupe
2001-2002 BMW Z3 M Roadster
2006-2008 BMW Z4 M Coupe

Configurations:

20-0070-00 Fuel Rail Kit, BMW S54, OEM Configuration
This configuration includes all the parts shown in the picture below. This makes a complete drop-in replacement for the OEM fuel rail. -1x Radium fuel rail with mounting hardware
-1x 8AN ORB plug
-1x 3/8" NPT plug
-1x 6AN male adapter
-1x PTFE fuel feed hose
-1x SAE Quick-connect adapter to attach to OEM fuel pressure regulator (shown below)



20-0070-02 Fuel Rail Kit, BMW S54
This basic kit includes only the fuel rail and mounting hardware. This is ideal when plumbing a custom high flow fuel system using an aftermarket regulator and custom fuel lines.



Front Port Options:
The front port of the Radium fuel rail is machined with 3/4"-16 (-8AN ORB) threads. Instead of using the included plug, a machined aluminum adapter can be installed enabling the use of a Radium fuel pressure gauge, as shown below.



Alternatively, a Radium Engineering fuel pulse damper can be used. Note: The high base (static) fuel pressure of the S54 engine requires the use of an FPD-XR (shown below).
