You would think. But if access was on a diagonal, they could also have wimped out and just inserted the tube the could get "around the corner" (so to speak) and it could have been shorter. If you can get a backlight on the tank, you might be able to get a visual on tube depth. Just a thought.
Our two water tanks are connected, fill one, draw from the other, so we only have a single fresh water sensor. And there's a 3-amp blade fuse in the circuit. I haven't seen a system with a 1/2 switch, but I wonder if each leg might have it's own fuse?
Also, WEMA (now KUS) switched from plastic tubes to stainless, sometime after at least 2003/2003. Would have thought that happened before your boat was built, but in any case, the plastic units failed a lot, and the stainless ones seem to last forever. (Well, at least 12 years so far...)
