Fuel Your Build With The Power It Demands

If you’re running big power through your 2015-2016 LML Duramax, the AirDog A7SABC515 II-5G 220GPH Lift Pump is a must-have upgrade. This system is built to support high-horsepower trucks that demand more fuel than the factory setup can handle. Whether you're running upgraded injectors, dual CP3s, or compound turbos, this pump ensures your engine gets clean, consistent fuel every time you put your foot down. It not only keeps up with the demand but also removes air and vapor from the fuel, helping protect injectors and improve combustion efficiency. That means smoother throttle response, better power delivery, and improved overall drivability. Installation is straightforward thanks to the included cradle bracket and direct-fit connections to the factory fuel lines. If you’re looking for a lift pump that can match the performance of your build, AirDog delivers the fuel and reliability your Duramax deserves.

High Volume Fuel Flow With Factory Fitment Simplicity

The AirDog II-5G DF-220 system is engineered specifically for 2015-2016 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L LML Duramax. It delivers 220 gallons per hour of fuel flow, making it ideal for heavily modified trucks that exceed 1000 horsepower. The pump mounts to the factory frame standoff location using a secure cradle bracket, keeping installation clean and stable. Fuel is pulled through a 5/8 inch draw straw installed in the tank, and pressure is sent directly to the factory 1/2 inch fuel line for seamless integration. Excess air and vapor are returned to the tank through the modified 12mm suction line, ensuring only clean fuel reaches the injectors. This system not only helps maintain consistent pressure but also reduces the chance of injector damage and low-fuel conditions during hard acceleration or towing. Built for reliability and performance, this lift pump is a critical piece for any high-output LML setup.
