Doug, if I'm not mistaken, I believe that there are two vent--valves-- (if you will) -- located on top of the fuel tank. The first one has two hoses--the filler hose and the hose that connects the two valves together. The second just has one hose, connected to the first. One of these may be blocked, or some kind of insect or animal, that likes gas vapors, built a nest in one of these vent valves. Your truck is a 2005 this sounds like a warranty issue. Let me know how you make out.
