Radium Parallel Fuel Rail Plumbing Kit w/DMR RA Regulator - Subaru WRX 08-14/STI 08-21/FXT SH/LGT 07-14 (EJ20/EJ25)
Application: Subaru Impreza WRX STI (2008-2021) - EJ25
Part Type: Underhood fuel rail plumbing kit (parallel feed) with MPR-RA multi-port regulator
Part Number: 20-0984
The Radium Parallel Fuel Rail Plumbing Kit complements a Radium Subaru EJ fuel rail installation by providing all of the underhood fuel plumbing. It interfaces with the factory feed and return hard lines in the engine bay near the LH strut tower, and all fittings, hose and an adjustable Radium fuel pressure regulator are included.
The parallel kit consolidates hoses and fittings for a cleaner engine bay. Feed and return lines enter the Radium MPR-RA multi-port regulator from the rear and exit the front to the fuel rails, with the regulator mounted to the LH strut tower on a stainless steel bracket. A 0-100 psi gauge is included for calibration, and if the factory piping has been replaced with aftermarket AN lines, the regulator-side fittings can be changed to suit.
