PORTS AND FITTINGS
The fuel rail ports are tapped for 8AN ORB.
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.
This kit is compatible with the 2007-2014 (S197) Shelby GT500 with OEM returnless or aftermarket return fuel systems.
Manufactured with a large internal bore, the fuel rails can support all necessary engine power requirements. They are CNC machined from solid 6061 aluminum, black anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted.
This kit offers a total of eight 3/4-16 (8AN ORB) threaded ports to allow plumbing of ancillary fuel system devices. In order to clear the supercharger's intake pipe, the LH fuel rail (shown above) features three ports. The lower center port for both rails are most commonly used for Radium Engineering fuel pulse dampers. The RH fuel rail (shown below) features all the ports from the LH side fuel rail with the addition of two top ports (5 total). The top front port is for the provided adapter that is used to mount the OEM fuel pressure sensor. The top rear port is commonly used for aftermarket fuel pressure monitoring. A variety of compatible 8AN ORB adapter fittings.
This kit is compatible with all fuel types including popular alcohol mixtures such as E85.
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’.
