Description
20-0569-02
The “conversion” fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors (not included). The fuel rail injector bores are 14mm ID. Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser engraved for a high quality surface finish. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85. Machined press-fit phenolic spacers are included to insulate intake manifold heat transfer.
The four billet injector seats are anodized and laser etched and provide a sealed receptacle for top feed fuel injectors. The seats are designed for injectors with 14mm lower O-rings.
For the 20-0569-02 conversion fuel rails, adaptable mounting brackets are included that permits a wide range of Subaru vehicles to be used.
Do NOT purchase “WRX Fitment” injectors. Below are some of the many fuel injectors that are a direct fit:

- Injector Dynamics ID1300-48-14-14
- Injector Dynamics ID1700-48-14-14
- Injector Dynamics ID2000-48-14-14
Kit includes:
- Black Anodized Laser Etched Aluminum Fuel Rails (x2)

Do I need a 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 oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle. The optional Radium 20-0176 fuel pulse damper can be used in any of the three -8AN ORB ports on these fuel rails.
