Radium Engineering Parallel Fuel Rail Plumbing Kit - Subaru WRX 08-14 / WRX STI 08-21

Description

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) 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.

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.
