I have a 1999 Tiara 4000 Express.  Neither the water tank nor the gray water tank levels were working.  I replaced the water sending unit with a KUS 17 and that is now working properly.  I now need to tackle the gray tank. Does anyone know what product model number I need? Also, there are two sending units in the tank, one is disconnected.  Any ideas on why there are two sending units?

Thanks, 
John

When you say gray water tank do you mean the one aft in the engine room or the black water tank under soul in aft cabin?

If it's gray water tank one is float for pump other is for high water alarm

Not the sea chest, the one in the aft cabin under the floor.

OK. Not freshwater, but black water under aft cabin sole? Have no clue where there is a gray water sending unit, or where a gauge would be to see data. Had to replace black water sender (waste tank) in August on a 2001 40 Express. Here is the guy that we contacted for that part:

I have two sending units. One has a hose vent as part of the sender, the other does not. The one without the vent is not wired up. I have a picture if you can give me an address to send it to.
