Usually if you have a EVAP issue or vent issue with the fuel tank you will have issues filling the tank up. If it is filling up my first guess wouldn't be vent issue. I've seen the rollover valve in the tank stick open and cause this issue. If it is easy to get to you might take the fill tube off the tank and check the valve in the tank and see if it is stuck open. If it is i don't think you can get the valve separate from the tank. Some of the newer Dodge Durango's had a recall for this issue. The fix was to replace the tank.
