water tank level monitoring

[esf]

I have a 1996 31 Open and the level gauge does not read for either the water or waste tanks when I press the button to select the tank.   The light is on indicating power.   I do get an high level on my waste tank when it is full.  The original was a Fireboy Xintex Liquid Level monitor LLM-2 system.  

Does anyone have suggestions on what to look for?  Also looking for recommendations on replacement systems as the Fireboy is no longer made.   

Thanks

Try the KUS products. Just replaced the sensor on my freshwater tank and works great with my original gauge. All you need to know is the length and how it mounts to the top (typically a 5-hole install). Super easy to hook up (just two wires) and like a $60 fix.
