The Pureflow AirDog II-5G A7SABC515 DF-220-5G Air/Fuel Separation System is the next generation in fuel delivery systems for your 2015-2016 GM 6.6L Duramax. The 5G is designed to be the most efficient, longest lasting, and quietest lift pump system available from AirDog.

The Airdog II-5G Fuel/Air Separation System features a 4-bearing motor with an intermediate shaft that improves reliability and reduces pump noise. A demand flow design allows the pump to only send the necessary amount of fuel to the engine. The 5G utilizes a diaphragm style fuel pressure regulator allowing the pump to be boost referenced and adjusted from 7-70 PSI.

The 5G system features larger 3/4-16 O-ring boss inlet and outlet ports. A 7/16-20 (-4) low-flow return is used to prevent aeration in the fuel being sent to back to the tank. A dual feed motor supplies fuel to both sides of the gerotor pump to decrease air bubbles that cause cavitation.

AirDog II-5G Features:

  • 220 GPH Pump
  • 4 Bearing Motor with Intermediate Shaft
  • Larger Ports Over Previous Pumps
  • Diaphragm Fuel Pressure Regulator
  • Demand Flow Design
  • Reduced Aeration From Low Flow Return

  • Hello, I see where it states this is for vehicles with 1000 hp or more. Will this work on a stock everyday driver or not? Thanks

    The 100 gph or 165gph would be a better product for that application. The 100gph will support up to 600hp and the 165 gph 800 hp.
