FUEL INJECTOR COMPATIBILITY
This fuel rail is compatible with factory or OEM equivalent fuel injectors. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Radium Engineering cannot specify any further injector dimensions other than stating ‘OEM equivalent’.

OVERVIEW
These fuel rails have the same mounting, injector spacing and fitment as the 20-0567-02. 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).
