Product Description

The AirDog A7SPBC259 II-5G DF-100-5G Lift Pump is engineered to enhance fuel delivery for 2001-2010 Chevrolet Silverado and GMC Sierra trucks equipped with 6.6L Duramax engines. With a robust 100 GPH flow rate, it supports stock to moderately modified engines, ensuring consistent fuel pressure and optimal performance.

This system effectively removes air, water, and particulates down to 2 microns, safeguarding your injection system components. The integrated diaphragm fuel pressure regulator maintains stable pressure, while the Demand Flow design recirculates unused fuel, reducing aeration and improving efficiency. Installation is straightforward with the included frame rail mounting system and comprehensive hardware kit.

By bypassing the factory in-tank lift pump and fuel filter housing, the AirDog II-5G provides a direct and efficient fuel supply to the injection pump. Whether you're towing, racing, or daily driving, this lift pump ensures your Duramax engine receives clean, air-free fuel for peak performance.
