Radium Series Subaru EJ Fuel Rail Plumbing Kit

The Radium Engineering Subaru EJ Fuel Rail Plumbing Kit is designed to compliment Radium Engineering Subaru EJ fuel rail installations. This is the Radium Series kit, and it is designed to interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the under hood fuel plumbing. All necessary fittings and hoses are included, along with an adjustable high-flow fuel pressure regulator.

This kit is compatable with all Radium Fuel Rails for the Subaru EJ engines (excluding 20-0499 Fuel Rails).

This kit is compatible with all Impreza (WRX/STi) platforms that use an EJ motor. For early vehicles with an engine bay mounted fuel filter, consult the installation instructions.

IMPORTANT NOTES

1. This kit Does  Not include a fuel filter.
2. This kit is compatible with Radium dual port injector fuel rail kit 20-0499.
3. Both kits are safe to use with alcohol fuels such as methanol, ethanol, E85 etc.
4. 4. Both kits use 3/8" (6AN) high pressure EFI fuel hose.

This kit interfaces with the factory hard lines near the LH strut tower using SAE quick connects or older hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) and Radium 0-100psi fuel pressure gauge are included.

The fuel pressure gauge can be installed at any of the 6AN junctions before the regulator using the included adapter. The 6AN swivel fuel rail fittings are low profile making them ideal for the tight spaces associated with the EJ motor. The variety of reusable Push-Lok hose ends permit customizing (such as adding a flex fuel sensor) making installation quick and painless.

The included 6AN fuel hose can be cut with standard tools and assembled without special skills. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided hose is resistant to all fuels including E85.
