AEM's High Volume Fuel Rails feature a 1/2-inch fuel bore capable of flowing enough fuel to support most high-horsepower applications. This large bore also dampens back pulses from injectors, and works perfectly with stock injectors. An additional 1/8'' NPT port is included for the factory fuel line, and the ends of the rail are pre-tapped to accept -06AN or -08AN fittings for users with custom fuel lines.
