radium ENGINEERING Fuel Rails (GM 6.2L LSA & LS9)

The fuel rail ports are tapped for 8AN ORB.

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.

The fuel rails are CNC machined from 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each fuel rail has six 8AN ORB ports, twelve ports in all.

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 fuel rails feature polished stainless steel brackets that attach to 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. Additionally, these rails have provisions for the factory injector clips.

This includes 2 black anodized fuel rails, stainless steel mounts, and stainless steel hardware. Adapter fittings are NOT included.
