If the vent is plugged up no air can enter the tank & it develops a vacuum. After that you probably have a plugged up fuel filter or the sock on the end of the fuel intake. The 47 doesn't come with a sock on the end of the tube so thats probably not it. It may have a shutoff valve under the tank. That can get clogged up also. Test the fuel pump. There are directions on fuel pump tests in the Tech-tips or the search on this website. Let us know how it turns out.
