New from Radium – the Fuel Rails for GM LS7. These fuel rails are CNC machined from 6063 aluminum and feature a large 0.69″ internal diameter bore to suit even the most fuel hungry engines. See more details below.

Official Release:

With over 500hp in stock form, the big 7.0 liter LS7 cannot be ignored. It uses a unique fuel injector orientation, which required a new ground-up fuel rail design. Like the LS1 fuel rails, these new LS7 fuel rails feature three ports (per rail) that are all threaded -8AN ORB. The center ports can be used with a variety of accessories. Radium offers a wide variety of adapter fittings that are compatible.

They feature a large 0.69″ internal diameter bore to suit even the most fuel hungry engines. 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.
