Radium Engineering Series Fuel Rail Plumbing Kit, DMR RA Regulator for Subaru WRX / STI / FXT / LGT EJ20 / EJ25

Radium Series Fuel Rail Plumbing Kit, DMR RA Regulator, Subaru WRX / STI / FXT / LGT (EJ20 / EJ25)

Application: All Subaru models with EJ20 / EJ25 (EJ2X) engines, incl. WRX, STI, Forester XT and Legacy GT
Part Type: Underhood fuel rail plumbing kit (series feed) with DMR-RA regulator
Part Number: 20-0978

The Radium Series 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.

This kit feeds the fuel rails in series and connects to the factory hard lines using SAE quick connects or the older hose barb connections. A Radium DMR-RA direct mount regulator and 0-100 psi gauge are supplied – the gauge can be installed at any 6AN junction before the regulator. Radium offers series and parallel kits and states both perform equally well; the choice comes down to preference.
