Radium Engineering Fuel Rails

Radium Engineering Fuel Rails for LS1, LS2, LS3, LS6, L76 and L99 Each LS fuel rail features 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. It is compatible with all fuel types including popular alcohol mixtures such as E85.  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 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. Thi
