water in gas, any idea anyone??

i own a 1987 Dodge Ram, with water in the gas tank, and my A as the same problem, probably a contaminated gas station, anyone has a good trick to solve that problem without draining all the gas in the tank, i tried some stuffs, but they still do it , thanks

Try some dry gas first

by asking around, super and moth balls(nephtaline) did the trick, super will had some octane and moth balls will suck up the excess water .....and changing gas station will prevent this to happen again( i hope !)
