These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02 (above). However, each fuel rail has an 8AN ORB “top port”, unlike 20-0567-02 which has a center lower port (picture below shown with Fuel Rail Adapter 20-0372).

The added clearance is necessary for the EJ207 and JDM EJ205 engines that have early AVCS solenoids with vertical connectors.
