Product Description

The AirDog A7SPBC262 II-5G 100 GPH Diesel Fuel Lift Pump System is a performance-oriented aftermarket upgrade designed to improve fuel delivery on 2015-2016 Chevrolet Silverado and GMC Sierra models equipped with the 6.6L LML Duramax engine. Unlike stock configurations that rely on the injection pump to pull fuel from the tank, this AirDog system supplies a consistent, air-free fuel feed directly to the engine. The air/fuel separation design removes vapor and contaminants, helping protect the injection system and improve overall drivability.

With a 100 GPH flow rating, integrated diaphragm regulator, and robust 4-bearing motor, the AirDog II-5G strikes a balance between stock fuel system performance and enhanced reliability for stock to moderately modified Duramax trucks. The complete kit includes all necessary wiring, plumbing, and hardware for a direct-fit installation that mounts to the frame in front of the fuel tank. This lift pump system helps improve throttle response, fuel pressure stability, and engine efficiency - making it a valued upgrade for Duramax owners seeking smoother operation and added peace of mind.
