radium ENGINEERING Fuel Rails (GM 7.0L LS7)

PORTS AND FITTINGS
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.

Manufactured with a large 0.69" internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. All end ports are machined with 8AN ORB (3/4-16 female) threads. The lower center ports can be used for optional adapters and are also tapped with 8AN ORB (3/4-16 female) threads.

The kit features polished stainless steel mounts permitting the factory hardware.

Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. Additionally, these rails have provisions for the factory injector clips.

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

INCLUDED:
-Black Anodized Laser Etched Aluminum Fuel Rails (x2)
-Stainless Steel Mounting Feet (x4)
-Stainless Steel Hardware (x8)

FUEL INJECTOR COMPATIBILITY
This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating 'OEM equivalent’'

FUEL RAIL PLUMBING
In comparison, the OEM GM LS7 uses and extra wide intake manifold. For fuel rail plumbing, a combination of current Radium Engineering parts can be used.
