The AirDog II-5G DF-165 (SKU: A7SABC509) is a high-performance 165 GPH lift pump system engineered for 2001–2010 Chevy and GMC Duramax 6.6L diesel engines. This system replaces the lack of a factory lift pump, delivering consistent fuel pressure, improved throttle response, and enhanced overall performance. It mounts to the frame rail using a sandwich plate system and connects directly to factory fuel lines for a straightforward installation. Ideal for moderately modified trucks, the AirDog II-5G system also removes air and vapor from diesel fuel, helping to protect your injectors and high-pressure pump.
