RADIUM ENGINEERING TOP FEED CONVERSION FUEL RAIL KIT

FUEL INJECTORS

There are two type of fuel rails made by Radium: upgrade rails and top feed conversion rails. Upgrade rails only upgrade the rail and the OEM fuel injectors can be reused. If an upgrade to the injectors is desired, they must be equivalent to the OEM injector, meaning they must be the same height and the upper & lower O-rings must match the OEM diameters and styles. Top feed conversion rails are used to convert a vehicle that has side feed (or sometimes air-assist) injectors over to a top feed injector.

This fuel rail is an upgrade rail. OEM or OEM equivalent injectors must be used.

OVERVIEW

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.

For injector height flexibility and thermal insulation, machined insulating spacers are included. Reference instruction manual for more information. The fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85.

These H-6 fuel rails are for the EZ30 (Phase-II) and EZ36 flat 6 engines. Each fuel rail has three 8AN ORB threaded ports (6 total). These rails are compatible with AVCS with ample clearance with the nearby AVCS solenoid.

NOTE: PHASE-II EZ30 ENGINE (ONLY). The front fuel rail port on the RH side cylinder head is very close to the AVCS. This port must be plugged using 14-0150 8AN ORB plug.
