I'm looking at a 2000 19 foot Stingray I/O with 4.3L V6 that was stored over the winter with only 1/4 tank of gas. 30 gallon tank. I'm concerned that there will be water/condensation in the tank and I am looking for oppinions on dry gas. Isopropyl? Methanol? Do they work? I didn't see a fuel/water separator. Thanks.<br /><br />Brian
