Part #: 20-0584
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.
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.
20-0584 FUEL RAIL PLUMBING KIT, SUBARU EJ, PARALLEL
Because of the regulator mounting location and OEM fuel filter placement, the parallel fuel rail plumbing kit is only compatible with the 2008+ Impreza (WRX/STi) and Forester platform. 
Because the hoses and fittings are consolidated, the parallel kit is a good option for cleaning up the engine bay. Each fuel rail is fed as shown in the photo above. The feed and return lines enter the Radium Multi-Port Regulator (MPR) from the rear and output through the front to the fuel rails.
As shown above, the regulator secures to the LH strut tower using the provided stainless steel mounting bracket. A Radium 0-100psi fuel pressure gauge is included for calibration. Fittings and 6AN hose are included to interface with the OEM feed and return hard lines. If aftermarket -AN hoses/lines have replaced the factory piping, this kit can still be used (contact us for details).
The contents of the 20-0584 kit are shown below.
