Product Description
The AirDog A7SABC514 II-5G DF-220-5G Air/Fuel Separation System is a high-flow diesel fuel system designed for 2011-2014 GM Duramax 6.6L LML trucks. Built with AirDog II-5G technology, this 220 GPH system helps deliver clean, air-free fuel to support improved throttle response, consistent fuel pressure, and better injector protection for stock, towing, performance, and high-horsepower Duramax applications.
