Radium Engineering Subaru EJ Engines Fuel Rail Plumbing - Parallel

20-0984

COMPATIBILITY
08-14 Subaru Impreza STi
15-21 Subaru STi

OVERVIEW
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 MPR-RA regulator 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 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 info@radiumauto.com for details).
