Not to be too obvious. . . but do you have a vent line coming off the top of the tank?

Sounds like you are fueling through the vent..., if so you need to fuel through the carb line, by taking the line off the carb, and fuel the model so the vent can vent...
Good luck

To me it sounds like your vent tube does not reach to the top of the tank. It vents until the fuel level reaches the bung and then it starts overflowing through the vent line. If your problem is not solved by what Bill said then check to see if the vent tube is positioned at the top of the tank. If you tried to fill through the vent line I would be surprised if you could get any fuel into the tank unless the bung is leaking air.
