Water in the fuel

Stored indoors, if you can call an unheated steel hangar indoors (at
least it's out of the rain) particularly in the spring where the
humidity is usually very high and temperature swings can be 50 or more
degrees between day and night although 30 is typical (50 day, 30
night The next 10 days are showing mostly 40's in the day and teens
to 20s at night) I have taken over a pint out of 25 gallon tanks that
were about 1/4 full.

Hmm... I don't understand this.

One cubic meter (about 264 gallons ) of saturated air at 32 degrees F.
contains about 5 to 6 grams of water vapor. The fact that the temperatures
were falling into the 20s indicates that the air had less moisture in it than
that. There couldn't have been even a gram of water in 17 gallons of air at
those temperatures.

Where was the water coming from?
