   Take the hose that moves the gasoline from the tank to the   
   fuel pump off and drain the gasoline tank. Then add more   
   clean gasoline and do that repeatedly until you don't get   
   any more water out of the tank.   
      
   All that gasoline that you get out can be put into a clear   
   glass jar and the gasoline decanted off from the water.

   Not with that amount of water.
