In the process of working on my vaccuflush system and holding tanks...

I have two holding tanks,port and starboard in front of each engine. Each tank has a round access plate with three sensors installed in each.

My level gauge (on my panel) stopped working so decided to pull one of the tank sensors out. Three floats at different levels. Two were missing the floats. So for sure that is my problem.

Does anyone have any data on the sensors?? I might as well replace all six and not worry about it again..

Who made them? Where to by them, etc..

Update: Did some research for this and decided to rebuild them myself. Online company wanted just over $200 for the 3" cap with the three sensors attached.

Amazon sold me the sensors for $6.97 each, did all six. The various levels are nothing more than 1/8" PEX pipe. The sensor attach to the bottom of the pipe.

All in all took about an hour. Now both holding tanks repot "empty", 1/2, and full.
 
Good for you! Did you take any pictures of the sensors or during your project? Mine have been acting up and I would love to do the same but don't know where to start. Some pics would be really helpful to know what I'd be dealing with. You could pm them to me if you like.
