Radium Engineering Fuel Rails, Top Feed Upgrade – Subaru Phase-II EZ30/EZ36

These high-performance Radium Engineering fuel rails are designed for Subaru’s Phase-II EZ30 and EZ36 flat-6 engines. With precision-machined 11 mm injector ports and thermal insulating spacers, they support increased fuel flow while minimising heat soak. Each rail features three 8AN ORB ports to accommodate a variety of plumbing configurations and fuel accessories.

Optimised for clearance with AVCS components, the rails retain full OEM functionality without modifications. For the front RH port, Radium recommends using an 8AN ORB plug (P/N: 14-0150) due to its proximity to the AVCS solenoid.
