One day I tried to fuel up and the pump kept shutting off. I blamed the pump and went to another service station, but I had the same result at the next station. I've never seen anything like it. I was hoping to fix it myself, but I have no idea what is wrong so I am going to take it back to the dealership. Of course, this happed when I was 700 miles over 36,000.
Just ran into this thread now. Too bad you are MIA. You should visit often dude and so should I. It appears you are having a venting problem such as a blocked or kinked vent tube
When you are filling an empty or partially empty vessel, the air occupying the empty portion of the vessel must be evacuated simultaneously or allowed to escape in order for another liquid to occupy the space the air was already occupying. It appears your tank is not venting properly and the air displacement is occurring deep down through your filler port, which is obstructed by the gas nozzle and the new gasoline entering the tank.
The vent nozzle, if I remember this right terminates in and around the gas filler port. Your vent pipes along with excess fuel return should be all clumped together around the sending unit on top of the tank. This is assuming your fuel pump is in the tank. You’ll have to drop the tank and follow the tubes to trouble shoot. If your truck was off roaded and sank in the mud, I would suspect one of the above conditions. Look for any obstruction of a small port around the filler port before you drop the tank since dropping the tank is a pain-in-the-neck kind of job. The vent pipe may even terminate about 2 to 3 inches inside the filler port. It just occured to me, the vent pipe has to terminate within and NOT outside the gas tank containment system or you'll smell fumes all the time and your gas would evaporate causing a safety hazard. It should terminate above the trap door which the gas nozzle pushes down upon entry. If you try to look at the filler port from underneath the truck, you will probably see the vent tube's exit point. See where it terminates and clear the obstructions, if any. Let us know what happens. Good luck.
