Nice try, but no it makes no difference. FWIW, I can hear the magnet "click" at the 4 gallon mark, but not at the higher 10 gallon mark.  The gauge just reads full.

  Not sure if this applies to your year van, but .... are you sure it's not a sodium/ion issue with your water?
  Adding a teaspoon of salt to the tank of water may "fix" your problem, if the water in your
  area is very pure, as in glacier or aquifer water.

    Hi folks:

    My water level sensor quit over the weekend, and from what I read in the archives this is a pretty common problem and relates to the center float, which is a magnet. Is there any way to test the system before I order a new one for a whopping $70? I have 89, so it's the later model float type. If anyone happens to have an extra one for sale, let me know.
