OVERVIEW
Radium fuel rails for EJ engines come in two styles. The top feed conversion rails fit OEM side feed manifolds and convert from side feed injectors to universal top feed injectors. The top feed upgrade rail kits install onto manifolds that are factory equipped with top feed injectors and are simply an upgrade of the rail, still accepting the OEM fuel injector.
Before ordering, make sure that you've matched your intake manifold by model to the correct fuel rail part number and closely follow the fuel injector compatibility information of that fuel rail to ensure that you order the correct parts.

As shown below, thermal insulating spacers are provided to protect from heat transfer. Each fuel rail has three 8AN ORB threaded ports (6 total). If the OEM fuel pressure regulator needs to be reused, 20-0303 can be used. A Radium Engineering 20-0776 fuel pulse damper can be installed into the center port.
Fuel Injectors are NOT included and must be purchased elsewhere.
To eliminate the Subaru air assist feature on the EJ251, the provided O-rings should be installed into the lower groove on the Bosch EV14 injectors.
To eliminate the Subaru air assist feature on the EJ22 (California spec only), 20-0816 (x4) injector seats as well as 14-0720 (x4) spacers, and flat head M8x1.25x60mm Screws (x4) are required.
