Radium Fuel Rails, Top Feed Upgrade, Subaru EJ

Note: Fuel Pulse Dampener (FPD) Not Included

Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminium, black anodised, and laser etched for a high quality surface finish.

These fuel rails are designed specifically for OEM or equivalent fitment injectors. For injector height flexibility and thermal insulation, 2 sets of machined phenolic spacers are included. All injectors must use 11mm diameter upper O-rings, just like the OEM Subaru injectors. Reference instruction manual for more information.

The fuel rails are compatible with all fuel types, including popular alcohol mixtures such as E85.

Product Info

This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.

These fuel rails have the same mounting and injector spacing as the 20-0577-02. However, these fuel rails feature a 8AN ORB port machined in the underside centre of each fuel rail.

NOTE: The centre port bulge can create an interference with early AVCS solenoids found in the EJ207 and JDM EJ205. If this is the case, use P/N: 20-0577-02.
