Radium Engineering Subaru parallelplumbing kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. Both kits interface 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). compatible.

IMPORTANT NOTES:
1. Neither kit includes a fuel filter.
2. Neither 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. Both kits use 3/8" (6AN) high pressure EFI fuel hose.

Because of the regulator mounting location and OEM fuel filter placement, the parallel fuel rail plumbing kit is only compatible with the 2005+ Impreza (WRX/STi) and Forester platform.
