Recommended for Install:
Fuel Rail Adapter 20-0372
Fuel Rail Install Kit 20-0478
Also Available:
Top Port Fuel Rails
Full Description:
Manufactured with a large internal bore, the Radium 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 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.
These fuel rails have the same mounting and injector spacing as the 20-479-02 (below). However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail.
Install Notes:
The center port bulge (shown above) can create an interference with early AVCS solenoids found in the EJ207 and JDM EJ205. Check out the Top Feed Upgrade with -8AN Top Port fuel rails if you have this issue.
Includes:
(2) Black Anodized Laser Etched Aluminum Fuel Rails
(4) 20mm Phenolic Thermal Insulating Press-In Spacers
(4) 15mmPhenolic Thermal Insulating Press-In Spacers
(4) Phenolic Thermal Insulating Press-In Bolt Washers
(4) Stainless Steel M8x1.25 Mounting Bolts
Fittings:
• The fuel rail ports are tapped for 8AN ORB.
• Additional fittings may be needed based on your specific application.
Ample space around the fuel rail port is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide
