RADIUM ENGINEERING TOP FEED FUEL RAILS
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
These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02, but each fuel rail has an 8AN ORB port on the top, unlike 20-0567-02 which has a center lower port. The added clearance is necessary for the EJ207 and JDM EJ205 engines that have early AVCS solenoids with vertical connectors.
