Radium Fuel Rail Plumbing, Subaru EJ, Parallel

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.
