PORTS AND FITTINGS
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 on the product pages can be used as a reference guide.

This rail is compatiable with the following BMW engines (M50 / M52 / M52TU / M54 / M56 / S50 / S52)
 
Fittings and accessores in pictures are not included. Only the rail itself.
