...water weighs 8.3 lbs/gallon
...gasoline weighs 6.1 lbs/gallon
...thus, water sinks to the bottom of a tank and the gasoline floats on top of it. This is why water accumulates at the bottom of a gas tank...and why military aircraft always had "drains" for gas/water from the lowest points in fuel tanks.
...however, water and ethanol are mutually miscable (dissolve in each other).
