Product Description

The AirDog A7SABC514 II-5G DF-220-5G Lift Pump is a premium high-flow diesel fuel delivery and air/fuel separation system engineered specifically for 2011-2014 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L Duramax LML engine. Designed for extreme performance needs (such as heavily modified engines or applications exceeding 1000 hp), this 220 GPH system provides clean, de-aerated fuel directly to the CP4 injection pump, significantly reducing the risk of cavitation and fuel starvation under load.

Featuring an integrated diaphragm fuel pressure regulator with boost compensation capability, the AirDog II-5G maintains stable fuel pressure while the "Demand Flow" design ensures only the required fuel is delivered to the engine and excess is recirculated through the filter base for continuous cleaning. The complete kit includes a frame-rail cradle bracket, high-flow suction tube, wiring harness, fuel lines, quick-connect fittings, and a high-efficiency fuel/water separator, making installation clean and reliable.

Fitment is confirmed for 2011-2014 Chevrolet and GMC Duramax diesel trucks with the 6.6L LML engine. This system supports both RWD and 4WD within the stated years and is ideal for drivers seeking enhanced fuel supply performance, better throttle response, and extended fuel system life in high-demand applications. 2025 coverage is not applicable for this legacy platform.
