This kit is compatible with the 2007-2014 (S197) Shelby GT500 with OEM returnless or aftermarket return fuel systems.
Each rail features a large 0.69" internal diameter bore to suit even the most fuel hungry engines. 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 anciliary 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 can be found HERE.
This kit is compatible with all fuel types including popular alcohol mixtures such as E85.

OPTIONAL:
20-0334-11 Fuel Rail Plumbing Kit, S197 Mustang
The plumbing kit allows for easy integration with the the OEM fuel system. Unlike others on the market, the kit does not reuse the awkward 180 degree feed line with the fuel rails fed in series. Instead, this kit eliminates any unnecessary fuel hoses that route over the top of the engine preheating the fuel. The kit plumbs the fuel rails starting from the OEM hard pipe near the firewall and feeds the rails in parallel for even fuel distribution with the use of our high flowing Y-adapter fitting. All hoses are high quality PTFE and are compatible will all fuel types including E85. Billet aluminum O-ring plugs are included for all unused ports on teh fuel rail.
Fuel Pulse Damper(s)
Do I need pulse dampers? The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, pulse damper(s) should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle. Radium -8AN ORB Fuel Pulse Dampers can be used on any fuel rail port provided there is applicable space.
Fuel Pressure Gauge
All three parts are required for installing a fuel pressure gauge on the RH fuel rail in the top rear port (20-0029, 14-0119, and 14-0332).
