Pretty easy to check the fuel tank vent, when you put gas into the tank, you should be able to hear and feel it venting, if not use an air hose and blow back through it. May be that the screen that covers the vent on the hull is clogged, in that case a good can of carb clear or the likes will clean it for you. You may have to remove the fuel sender from the tank and take a look with an inspection light. If the tank is full of junk, as mine was, it does not take a lot of the small particle to clog the filter and or pick if there is a screen on it. My pick up tube in the original tank unscrewed from the tank and the ends a "V" notch on the bottom, no screen. I use a small HONDA/RACOR filter and it is a 10 micron and it was clogged.
