Radium Engineering GM LS9/LSA Engine Fuel Rails

Product Details

Radium Fuel Rail Kits are CNC machined from solid 6061 aluminum and black dipped anodized for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85. The Radium fuel rail is the first and only on the market to support an (optional) fuel pulsation damper. The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a pulse damper should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle.

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.

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 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, as shown below.

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