PORTS AND FITTINGS

The fuel rail ports are tapped for 8AN ORB.

8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
8AN ORB Fuel Pulse Dampers can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

Scroll to the bottom of this page to see details about the 20-0478 Fuel Rail Plumbing Kit.


Reference the chart below to be sure the proper fuel rails are ordered.

The "conversion" fuel rails convert the OEM side feed fuel injector setup to top feed allowing the use of high flow fuel injectors (not included). The fuel rail injector bores are 14mm ID. 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 engraved for a high quality surface finish. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85. Machined press-fit phenolic spacers are included to insulate intake manifold heat transfer. Two sets of spacers are included to accomodate popular 34mm or 48mm height universal fuel injectors from popular manufacturers. DO NOT purchase "WRX Fitment" injectors. See more information about injector fitment below.

The 20-0335 kit included adapter brackets (shown above), which are required for certain applications. See fitment chart above for details.

The four billet injector seats are anodized and laser etched and provide a sealed receptacle for top feed fuel injectors. The seats are designed for injectors with 14mm lower O-rings.



20-0168-02 FUEL RAILS, TOP FEED CONVERSION, SUBARU EJ

For the 20-0168-02 conversion fuel rails, 2 sets of the press-fit phenolic spacers (8 total) and matching hardware are included to suit different height fuel injectors. Use the tall spacers and longer mounting bolts to accomodate this size injector:

20-0478 Subaru Fuel Rail Plumbing Kit for EJ Engines
This engine bay plumbing kit is designed to be used with all Radium EJ fuel rails and includes all the necessary fittings, hose and other components to finish the installation and have a complete operating system.  This kit plumbs the fuel rails in series, beginning and ending at the factory hard lines near the LH strut tower.  It is compatible with all factory hard lines, whether SAE quick connect or hose barb connections. An adjustable Radium Direct Mount Regulator (DMR) is included along with a Radium fuel pressure gauge to calibrate the DMR. The 6AN swivel adapter fittings for the fuel rail ports are low profile making them ideal for the tight spaces associated with the EJ motor. Pushlock hose-ends are easy to work with, making installation quick and painless. A variety of hose-ends are provided so the installer can custom tailor the fuel line routing for their specific vehicle. A parallel feed system is not possible with this kit.


The fuel hose included in this kit can be cut and installed with standard tools and without special skills. Unlike standard low-quality rubber fuel hose that degrades with alternate fuels, the provided Vapor Shield hose is resistant to all fuels including E85. Furthermore, the hose has a thermoplastic armor layer that guards against unwanted vapor permeation (gas smell). And unlike PTFE, this fuel hose helps absorb absorbs unwanted fuel injector pulses and has an easy to work with bend radius.


The kit includes all of the components shown below:
-Direct Mount Regulator
-6AN PushLok Hose Ends
-6AN Adapter Fittings
-SAE Quick Connect Fittings
-3/8" ID Vapor Shield EFI Hose
-Stainless EFI Hose Clamps

Rail conversion
Fitted really easy and worked well with my ID1050X injectors... only tiny thing was the fittings could have been smoothed out inside instead of sharp step...
