Its a good thing to break up what may have gotten into your tank from time to
time any ole way. Go to your local dollar store and get some de-natured
alcohol and pour the stuff into your tank. Or you can go to the local parts
store and pay $ 2.79 or more.
As for as testing for water....if you have a glass bowel filter that came on
the older vehicles you would be able to see the water/glass line...if there
is water.
