Description
The EVO 4-9 Billet Fuel Rail features a large 0.69″ ID bore to suit even the most fuel hungry engines. The rail is CNC machined from solid 6061 aluminium, media blasted, black-dipped anodized and laser etched 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 pulse 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 pressure pulses and help to stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle or mysterious stumbling due to lean conditions.
Radium Engineering Fuel Rail Kits are available in two configurations:
- Rail Only- All fittings must be purchased separately
- OEM Configuration- This option includes everything required to simply unbolt and replace the OEM fuel rail, exact items as shown above in the picture
Optional:
- Fuel Pressure Gauge- billet adapter fitting is included to replace the plug in the top port. The gauge then screws into this billet adapter fitting. The location of this port was strategically placed for the gauge to be easily viewed.
- Fuel Pulse Damper (FPD-R)
