I went to Menards tonight after we filled the tank with gas, so that I could get a fill on LP. The girl screwed the nozzle on the fill port and pulled the trigger, gas shot out the vent, so she tried ...
well folks, went to Flying J today to see if they could fill this thing, and she did. When I took my fill cap off she said it's missing some piece on it, I assume a gasket for a nozzle that goes over the outside threads of the fill port. She then grabbed a fill nozzle that goes to the inside of the fillport, screwed it tight and turned the pump on, 18 gallons latter it was filled and off we went. Is mine old school and only able to be filled with the internal thread type fill nozzle?
