Thoroughbred Diesel Part #: PFTAIRDOGII5G

The Pureflow AirDog II-5G Air/Fuel Separation System is the newest generation in fuel delivery systems for your diesel. The 5G is engineered to be the longest lasting, most efficient, and quietest lift pump system AirDog has to offer.

The AirDog II-5G features a 4-bearing motor with an intermediate shaft that reduces pump noise and improves reliability. The demand flow design allows the pump to only send the necessary amount of fuel to the engine. A dual feed design supplies fuel to both sides of the gerotor pump to decrease air bubbles and cavitation.

AirDog II-5G Features:

  • 4 Bearing Motor with Intermediate Shaft
  • Larger Ports Over Previous Pumps
  • Diaphragm Fuel Pressure Regulator
  • Demand Flow Design
  • Reduced Aeration From Low Flow Return
  • Relay Control Wiring Harness
  • All Required Fuel Fittings
  • All Require Fuel Lines
  • Mounting Brackets and Hardware
  • Installation Manual

  • Has anyone every put one of these systems on a Mack semi with a Mack engine ? The reason I am asking is because I have an 2004 Mack with the Mack 460 engine that is getting air in the system and maybe this pump would be enough pressure to keep that from happening
