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 backpressure pulses from injectors, and works perfectly with stock injectors. An additional 1/8'' NPT port is included to accommodate a nitrous set up or fuel pressure guage. A custom fuel line fitting is included for the factory fuel line, and the ends of each rail are pre tapped to accept -6AN or 9/16"x18 fittings for users who want to use custom fuel lines. Key Features: * No additional parts required for installation. * Specifically engineered for each application. * O.E. fuel pressure regulator, or AEM adjustable fuel pressure regulator, mounts directly to rail. * Comprehensive installation instructions, hardware, fittings and injector O-rings included. * Manufactured and assembled in the USA.
