They are CNC machined from 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each fuel rail features six 8AN ORB threaded ports (12 total) that can be used for optional adapters.

NOTE: It is advised that the fuel rails be mocked up on the engine before adapter fittings and fuel delivery accessories are purchased. This is necessary to check clearance of surrounding engine components which may interfere with accessing some of the fuel rail ports.

The kit features polished stainless steel brackets that attach to the factory fuel rail mounting points. No vehicle modifications are required.

Like the OEM fuel rails, the injector bores are 14mm ID and are compatible with factory fuel injectors. This fuel rail kit is also compatible with any aftermarket injector that is designed for fitment with the OEM fuel rail.

Additionally, these rails have provisions for the factory injector clips, as shown in image #.

This kit is compatible with all fuel types including popular alcohol mixtures such as E85.



The fuel rail ports are tapped for 8AN ORB. and 12 are required for these fuel rails

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.
