    Top Feed Fuel Rail Conversion Kit by Radium Engineering

    This fuel rail kit converts 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. Each rail features a large internal bore to suit even the most fuel hungry engines. They are CNC machined from solid 6061 aluminum, black anodized, and laser engraved for a high quality surface finish. All 3 ports on each fuel rail are tapped with 8AN ORB (3/4"-16) threads

    Machined phenolic mounting spacers and washers are included to completely isolate the fuel rail from heat transferred from the TGV housings and mounting bolts. Two sets of these press-fit phenolic spacers (8 total) and matching hardware are included to suit different height fuel injectors. The kit is designed for specific upper and lower O-ring spacing, as depicted below.

    The 4 billet injector seats are anodized and laser etched and are designed for 14mm diameter lower O-ring injectors. Use the tall spacers and longer mounting bolts to accomodate 57mm injectors. Use the shorter spacers and mounting bolts to accomodate 42.5mm injectors.

    The 20-0168-01 kit includes enough to plumb the rails in "Parallel, Flow-Through" or "Series". Refer to the More Details tab above for more information. If -8AN male fittings are required, they can be purchased here 14-0152. Two of the plugs can be used if the fuel rails will be plumbed in "Parallel, Dead End", as shown. The other two plugs can be used for the lower center ports if a fuel pulse damper is not used.

    Features

    • Black Anodized Laser Etched Aluminum Fuel Rails
    • Green Anodized and Laser Etched Injector Seats
    • Phenolic Thermal Insulating Press-In Spacers
    • Phenolic Thermal Insulating Press-In Bolt Washers
    • Stainless Steel M8x1.25 Mounting Bolts
    • Black Anodized Aluminum 6AN Male Fittings (if purchased w/ fittings)
    • Black Anodized Aluminum 8AN ORB Plugs (if purchased w/ fittings)

    Please Note: The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a pulse damper should be used (especially with high flow injectors). The optional Radium 20-0176 fuel pulse damper can be used in any of the three -8AN ORB ports on the Subaru fuel rails.
