Well nuts would be the ideal solution except that the hole is at a corner and I would have to drill a much larger hole which means I would most likely destroy part of the vertical wall of the tank.
Taking a page off the golf tee idea I went to Ace and bought a 1/4" wood dowel and hammered it into the hole. It has reduced the flow to just a few drops and I'm hoping that as the wood swells it will completely plug the hole for the time being. Upon my return at the end of next month I will be forced to bite the sour apple and drop the tank for a permanent fix.
