High Flow Billet Fuel Rail

Custom billet machined 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, -8, or -6AN feed fitting and a -10, -8, or -6AN return...whichever combination you like.

Billet rails come with stainless steel hardware included.  Fits OEM body injectors.  Some small body injectors like the ID1000 EV14 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.
