Radium Fuel Rail, BMW M50 M52 M54 S50 S52

This Radium Engineering fuel rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. They are compatible with all fuel types including popular alcohol mixtures such as E85. Like the OEM fuel rail, the fuel injector bores are 14mm ID so factory injectors can be used, or any aftermarket injector with the same height and O-rings sizes. Furthermore, provisions for the OEM injector retaining clips are provided.
The fuel rail has three 8AN ORB threaded ports in total. Optionally, Radium FPD-R or FPD-XR fuel pulse dampers fit in the center fuel rail port. Optionally, Radium DMR fuel pressure regulator can be used on either end.
This fuel rail features three 8AN ORB ports, one in the center and one at each end. O-ring style fittings must be used in these ports. No fittings are included with this fuel rail and must be purchased separately. 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. To verify clearance, the dimensional drawings can be used as a reference guide.
