HELP! I can't fuel the truck.

[dirtfinder]

On a road trip and having major issues filling the tank. The gas pump nozzles are constantly shutting off as I try to fill the tank. Took me 20 minutes at the last stop. I tried three different nozzles so I know its not the gas pump.

I looked down the filler tube and up from under the truck but don't see anything that looks problematic. What should I be looking for? Any idea what is causing this?

Check the charcoal cannister that is part of the evap system. Had the same thing happen to me last year. A spider had built a web inside one of the ports. Blowing it out with air fixed the problem.
