that is simply not true. ethanol will not attract water out of the atmosphere
Sorry but it does. Hydrogen bonding causes pure ethanol to be hygroscopic to the extent that it readily absorbs water from the air.
Unless you are leaving it outside in the rain with the cap off...once it draws the moisture from the air in the tank, it's largely done.
I ran the math one time for the 220gal tank on our boat and assume the air changes over 100% once per day due to temperature fluctuation (it won't), over 6 months it was 2-3cc. On a tiny 1gal generator tank, it will be a tiny fraction of that.
If you got water in the tank, it probably came with the fuel.
