I'm confused. Why did you take it to Cummins in the first place? If it wouldn't start, why did you assume it was the fuel filter? Why do you assume it is the air filter now? There are many, many things that can cause a generator not to start. The air filter is the last thing I would suspect.
If you want to give us some history and specifics on the make/model, and exact problems, I'm sure someone can give you specific things to ckeck. Otherwise, you might as take it back and have Cummins figure it out and charge you accordingly.
