Official Release :

PureFlow AirDog is once again transforming the diesel market with the release of the new AirDog II-4G, the next generation of the fuel air separation system.

Hands down, it is the quietest pump on the market. The newly designed fuel air separation system offers the same positive air, particulate, and water separation you expect from an AirDog fuel system. Installation is straightforward with easy to follow manuals and “plug and play” quick connect parts. Within a matter of hours you will experience the benefits of pure diesel fuel. The AirDog II-4G pump is only available through an AirDog certified dealer. Advancing the AirDog Tradition with the 4th Generation Fuel System! The AirDog II-4G system improves engine performance by, maintaining correct injection timing, elimination spray pattern disruption, and allowing for a full power stroke and complete burn.
