Social Share:


This is the AirDog II-5G DF-165-5G fuel system for the 2001-2010 Chevy/GMC Duramax 6.6L Diesel. This diesel lift pump mounts to the frame rail using the supplied sandwich plate mounting system. The suction side hooks up to the factory suction fitting in the fuel module. The pressure side connects directly to the factory injection pump feed line on the frame. The AirDog Air/Vapor return is sent back to the tank through a filler neck tee. This system is one of our easiest installations. Our Duramax kits usually see the largest performance gains as these trucks do not come with a lift pump from the factory. This is a 165GPH (Gallon Per Hour) lift pump system for moderately modified trucks. Features:

  • Reduced Aeration From Low Flow Return
  • All Necessary Wiring, Plumbing & Installation Hardware Included
  • Integrated Diaphragm Fuel Pressure Regulator
  • 12-Gauge Wire Harness
  • Demand Flow Design Recirculates Fuel Back Through The Filter Base
  • Larger Ports Over Previous Pumps
  • Lifetime Limited Warranty
  • Reliable & Quiet 4G Motor Technology
  • 165 GPH Fuel Pump
  • Better Fuel Flow At Pressure
  • Enhances Engine Effciency
