Went and looked it up and I think "No" is the answer to your question.
From the website:
The new compact AirDog™ provides the most effective technology designed specifically for diesel pickups to remove water, particulates, vapor and entrained air from diesel fuel. The AirDog™ replaces the Cummins factory lift pump and filter system, and enhances the fuel delivery of the Powerstroke
and Duramax with a commercial duty system.
