Radium Engineering subaru top feed rails.The auxiliary port is located on the top surface of the fuel rails, making this setup ideal for applications that would experience clearance issues with AVCS components. For applications that were top-feed injectors from the factory. CNC machined, anodized and compatible with E85.

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
