I would look to see if you can see any fuel sitting somewhere on the engine.
That was going to be my first suggestion. I had a problem with the filter gasket leaking when I got my truck. A new filter and gasket and some time to let the valley dry up fixed mine.
I also get some exhaust smell in the cab now and then but if you get the wind blowing the exhaust back towards the HVAC intake I dont really think theres anything you can do about that...
