How much water do you think you have? I would put in a specific gas dryer treatment and try to drive it.

You could try draining some of the gas. After letting it sit for a day or so the water should pool at the bottom of the tank. You could pull a pressure line at the pump or filter and turn on the ignition and let the pump run a half gallon of so out of the tank. The filter would probably be a good spot since there may be some water there since it is the lowest spot in the system.
