At AirDog®, quality goes beyond material selection or industry standards. They measure superior quality through customer satisfaction. It is for this reason that AirDog hand assembles each and every fuel pump as if it were going on our own truck. Their manufacturing process hinges on consistency and integrity. This means all manufacturing processes from ordering raw material to final testing of the product adhere to stringent quality checks to ensure they offer value and elevate the customer experience.  AirDog works with industry thought leaders, cutting edge technology, and an engineering staff with 30+ years of experience to bring automotive enthusiast innovative products they can depend on. Through Research and Development, AirDog's goal is to continue the advance of the patented AirDog® fuel system with unique perspective of diesel applications. We take pride in bringing you the most up-to-date information and technically advanced diesel products in the market.

The AirDog® II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator allows for more fuel pressure adjustability, offers better fuel flow at pressure, and can be boost compensated! This system has larger porting to allow less cavitation and noise at the inlet of the higher flowing 220GPH pumps. All AirDog II-5G systems come with improved wiring harnesses and connectors as well! The wiring harness is now 12ga from the battery all the way to the internal connections in the motor. A Metri-Pack 280 connector replaces the Deutch 2 pin connector which allows more more current flow without creating excessive heat. All other connectors in the harness are weather pack to keep the elements out. This system has the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also retains the "Demand Flow" of the older AirDog II variants. Demand Flow means whatever fuel the injection system does not consume gets recirculated back through the filter base.
