Radium Engineering PLUMB KIT SUBARU EJ

Fuel Rail Plumbing Kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. These kits interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the under hood fuel plumbing. All necessary fittings and hoses are included, along with an adjustable Radium Engineering fuel pressure regulator. Two plumbing kits are offered; one that feeds the fuel rails in series, and another that feed the fuel rails in a parallel configuration. Both kits perform equally well. The end decision is based on personal preference. Scroll down for details on each kit. 20-0978 Fuel Rail Plumbing Subaru EJ Series This fuel rail plumbing kit interfaces with the factory hard lines near the LH strut tower using SAE quick connects or older hose barb connections. A DMR-RA regulator (shown below) and a 0-100psi fuel pressure gauge are included. The fuel pressure gauge can be installed at any of the 6AN junctions before the regulator using the included adapter. The 6AN swivel fuel rail fittings are low profile making them ideal for the tight spaces associated with the EJ motor. The variety of reusable PushLok hose ends permit customizing (such as adding a flex fuel sensor) making installation quick and painless. The included 6AN fuel hose can be cut with standard tools and assembled without special skills. 20-0984 Fuel Rail Plumbing Subaru EJ Parallel 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 by changing the fittings on the regulator where the feed and return lines meet.
