I had had a blockage, but it was an ice pellet: no idea where the water had come from- my fuel checks never show water (can only think that somehow the tractor came with water in the tank, or it was introduced by the dealer). As OP is in Florida, and it's only the first of October, I figured that ice pellets wouldn't be in this equation: but should others come along I figure the mention of them/it might be of benefit.
Not sure if one can dip a clear, flexible tube down toward the bottom and next to the outlet and, after reaching that spot cap (thumb over tube's hole) the end of the tube and raise it all up to see if it pulls up anything. I've got a USB bore-scope camera thingy (operable via my smart phone) and think that this might be another case where it could be applied.
