However, each fuel rail has an 8AN ORB "top port", unlike 20-0567-02 which has a center lower port These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02 (above). Stainless Steel M8x1.25 Mounting Bolts (x4)Ģ0-0577-02 FUEL RAILS, TOP FEED UPGRADE, SUBARU EJ, TOP PORT Thermal Insulating Press-In Spacers, 20mm (x4)

Black Anodized Laser Etched Aluminum Fuel Rails (x2) If this is the case, use P/N: 20-0577-02 below. NOTE: The center port bulge can create an interfere with early AVCS solenoids found in the EJ207 and JDM EJ205. However, these fuel rails feature a 8AN ORB port machined in the underside center of each fuel rail. These fuel rails have the same mounting and injector spacing as the 20-0577-02. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’. If upgrading fuel injectors, consult your aftermarket injector supplier for details. This fuel rail is compatible with factory or OEM equivalent fuel injectors. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.Ģ0-0567-02 FUEL RAILS, TOP FEED UPGRADE, SUBARU EJ

Reference instruction manual for more information. All injectors must use 11mm diameter upper O-rings just like the OEM Subaru injectors. For injector height flexibility and thermal insulation, 2 sets of machined insulating spacers are included. These fuel rails are designed specifically for OEM or equivalent fitment injectors. Parallel kits are a little tidier, but it is all preference.Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish.

RADIUM FUEL RAILS STI SERIES

There are no performance differences between the series and parallel kits. Please Note: This does not include fuel rail.

Replaces old fuel delivery components that may be worn out.

Adjustable Radium Direct Mount Regulator (DMR) and Radium 0-100psi fuel pressure gauge are included.

Compatible with different fuel types like E85, methanol, etc.

Parallel or Series options are available.

Includes all necessary fittings are hardware.

The feed and return lines enter the Radium Multi-Port Regulator (MPR) from the rear and output through the front to the fuel rails. Each fuel rail is fed as shown in the photo above. The contents of the 20-0578 kit are shown in the photo below.īecause the hoses and fittings are consolidated, the parallel kit is a good option for cleaning up the engine bay. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided hose is resistant to all fuels including E85. The included 6AN fuel hose can be cut with standard tools and assembled without special skills.

The variety of reuseable PushLok hose ends permit customizing (such as adding a flex-fuel sensor) making installation quick and painless. The 6AN swivel fuel rail fittings are low profile making them ideal for the tight spaces associated with the EJ motor. The fuel pressure gauge can be installed at any of the 6AN junctions before the regulator using the included adapter.

An adjustable Radium Direct Mount Regulator (DMR) and Radium 0-100psi fuel pressure gauge are included.

This kit interfaces with the factory hard lines near the LH strut tower using SAE quick-connects or older hose barb connections. The end decision is based on personal preference. Two kits are offered one that feeds the fuel rails in series, and another that feeds the fuel rails in a parallel configuration. All necessary fittings and hoses are included, along with an adjustable high-flow fuel pressure regulator. Both kits interface with the factory feed and return hard lines in the engine bay (near the LH strut tower) and provide all the underhood fuel plumbing. These plumbing kits are designed to compliment Radium Engineering Subaru EJ fuel rail installations. Multiple Subaru Fitments Fuel Rail Plumbing Kits by Radium Engineering
