Actually filling a tank with water is a comon way to test for leaks.
Particularly with large tanks where filling the tank with fuel can be costly
and dangerous. It's not like a large fuel tank doesn't get a little water
in it from time to time.

WRONG

Do *not* fill a fuel tank with the wrong kind of fuel, or water. I think
most people would be smarter than to do this anyway, but I felt I should
speak up just in case.

Note to rec.boats regulars- I generally skip K.Smith's posts but checked
this one.
