That would be the vent hose. If you spend a lot of time in the mud and water, you can re-route that hose up to the inner fender a little higher. (although by design, the "s" shape is not supposed to allow for water intrusion, but i wouldn't trust it in deep submersion)

I have always re-routed it on all my trucks, yet i still haven't done any major creek crossings.......

There is a hose for your transfer case and rear axle as well. Guys who spend a lot of time in deep water or mud run these hoses up higher, in order to stop water ingestion or clogging of the tube.
