PORTS AND FITTINGS The fuel rail ports are tapped for 8AN ORB and 1/8 NPT. 8AN ORB Adapter Fittings. 8AN ORB Direct Mount Regulators. 8AN ORB Fuel Pulse Dampers. Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

They are CNC machined from 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Each fuel rail has 3 (6 total) 8AN ORB threads.  The physical profile features maximized clearance with the upper intake manifold and the distributor, while supporting maximum flow. Because of this innovative design, the fuel injectors are installed in an exact perpendicular orientation with respect to the LIM injector seats, exactly like OEM. No spacers required. These fuel rails are compatible with all fuel types including popular alcohol mixtures such as E85. INJECTOR COMPATIBILITY Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. If upgrading fuel injectors, consult your aftermarket injector supplier for details. Bosch EV14 injectors are ideal as they promote extra connector to fuel rail clearance. Radium Engineering cannot specify any further injector dimensions other than stating "OEM equivalent".
