The Radium Engineering plumbing kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. This kit interfaces with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the underhood fuel plumbing. All necessary fittings and hoses are included, along with an adjustable high-flow fuel pressure regulator.
Two kits are offered; one that feeds the fuel rails in series, and another that feed the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference. Scroll down for details on each kit.
Both kits are compatible with all Radium Fuel Rails for the Subaru EJ engines (excluding 20-0499 Fuel Rails).
IMPORTANT NOTES:
1. Kit does NOT includes a fuel filter.
2. This kit is NOT compatible with Radium dual port injector fuel rail kit 20-0499.
3. This kit is safe to use with alcohol fuels such as methanol, ethanol, E85 etc.
4. This kit uses 3/8" (6AN) high pressure EFI fuel hose.
20-0578 FUEL RAIL PLUMBING KIT, SUBARU EJ, SERIES
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.
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 reuseable PushLok 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.

Would be five stars if they included pipe thread tape and loctite. For the price it would have been nice to come with a 6an wrench. Overall good product! Looks very nice!
This fuel kit is awesome and is very easy to install
