I got the code P0410 on my truck. I checked on the fuse when it first popped up and the fuse was blown. So I replaced the fuse and that kept the code away for only a few days. Now checking on the 30 amp fuse again, it’s not blown. I’m trying to get an idea of what’s going on and I could use anyone’s insight on this. The truck has also never been near water.
Also, does the relay besides the fuse have anything to do with the air pump?

What year and motor? You don't have to be around water for the pump to get water in it. Rain water can make its way in there. They rerouted the vent later on up top to help eliminate it. As mentioned, apply power/ground to the pump and see if it runs. If it blew the fuse, my bet is the pump is bad.
