Was giving my Versatile 375 a look over and noticed the plastic hose on the tank on the door side. It looks like a sight tube but you couldnt see thru it. It runs from top to bottom on the side of the tank.Anyway I pinched the hose and it cracked and started to leak and the tank was full. Grabbed a few bolts and a knife and cut it and plugged it and went to town and replaced it with a rubber hose. I recommend you look at yours.
