I think we may be on the wrong track here. If water is suspected in a cars
fuel system, you add ethanol to get rid of it. The alcohol combines with
the water and then with the gasoline. With enough ethanol present, the
water/ethanol mixes with gasoline and is burned away.


A common method to test gasoline for presence of alcohol is to put a small
amount of water, about 10% by volume, in a test tube or similar container.
Add suspect gasoline and shake. If the water level appears to rise, it's due
to alcohol coming out of solution with the gasoline and joining with the
water. If there's no alcohol, the water level remains the same.
