Radium Engineering Subaru Fuel Rail 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.

FUEL INJECTOR COMPATIBILITY
OEM Injectors-The Radium Engineering fuel rail features 11mm injector bores making it compatible with the factory Subaru EZ30 Phase-I "air-assist" fuel injectors. No modifications are needed. If preparing to use aftermarket fuel injectors, read below.

Aftermarket Injectors-The Phase-I EZ30 uses air-assist emissions equipment. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. In order to use universal aftermarket fuel injectors, these cylinder heads require the provided Radium injector seats. When these injector seats are installed into the air-assist cylinder heads, an aftermarket injector that is 48mm long with 11mm upper O-ring and 14mm lower O-ring must be used. The following universal injectors have been verified to be compatible. However there are others on the market that will work that are not listed here

OVERVIEW
These H-6 fuel rails are for the original Subaru EZ30 "Phase-I" flat 6 engine. This engine is denoted by having a single exhaust port per bank. These engines also incorporate the Subaru air-assist fuel injection system.

Each fuel rail has three 8AN ORB threaded ports (6 total). To reuse the OEM FPR, use 20-0301.
