Billet M50 Manifold Fuel Rail
Custom billet fuel rail for the BMW with M50 intake manifold. A must have for a high horsepower car or when converting to E85 fuel with larger volume demands.
This fuel rail is machined for -8 AN ORB o-ring fittings on feed and return sides but will accommodate larger or smaller feed and returns with your choice of supplied adapters. You may choose a -10 AN feed fitting and a -6 AN return...or whatever combination you like.
Billet mounts and stainless steel hardware included. Fits OEM body injectors. Some small body injectors like the ID1000 may require a spacer on the bottom of the injector.
Spacers serve 3 purposes.
1. Spacers will keep the injector stable in the rail.
2. Limit the injector from seating too deep in the OEM intake manifold which will create a boost leak.
3. Keep the injector seated in the rail and eliminate the chance of a dangerous fuel leak.
*Fuel rails are only available in bright BLACK anodized. Available with -6 -8 or -10 straight male adapter fittings.
