Description

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 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 insulating 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.

Fuel rail adapters and fuel rail plumbing kits sold separate.

20-0577-02 FUEL RAILS, TOP FEED UPGRADE, SUBARU EJ, TOP PORT

These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02 (above). However, each fuel rail has an 8AN ORB “top port”, unlike 20-0567-02 which has a center lower port (picture below shown with Fuel Rail Adapter 20-0372). The added clearance is necessary for the EJ207 and JDM EJ205 engines that have early AVCS solenoids with vertical connectors.

Includes

  • Black Anodized Laser Etched Aluminum Fuel Rails (x2)
  • Thermal Insulating Press-In Spacers, 20mm (x4)
