I can't get under my 81 enough to get a good pic but this sketch is the way my tank vent is..on the tank there's 2 nozzles..one for fill one for vent...on the fill end there is a 90* fitting welded onto the main fill tube on the upper side of the tube and close to the mounting flange..if the gas nozzle is inserted in the filler the 90* elbow is behind the nozzle tip
