There is a breather that follows the filler tube to the tank. Its purpose is to allow air to exit the tank as fuel enters. Chances are there is an obstruction or damage to it. CHeck it. You may want to get a wire or something you can run through the hose to check for obstruction.

Let me know what you find.
