Radium Top Feed Upgrade Fuel Rails - Subaru Liberty/Outback 04-19 (EZ30/36 H6)

Radium Top Feed Upgrade Fuel Rails — Subaru Liberty / Outback (2004-2019) EZ30 / EZ36 H6

These Radium Engineering H-6 fuel rails are a direct upgrade for the EZ30 (Phase II) and EZ36 flat-six engines found in the Subaru Liberty and Outback from 2004 onwards. CNC-machined from solid 6061 aluminium with a black anodized and laser-etched finish, they feature a large internal bore capable of supporting all necessary engine power requirements — from mild street builds through to high-power forced induction applications.

Each fuel rail features three 8AN ORB threaded ports (six total across both rails), providing maximum flexibility for fuel system plumbing. The design provides ample clearance with the nearby AVCS solenoid for a clean, interference-free installation.
