Fresh and Waste Water Gauge

[jhhall]

I had a similar problem on my 2006 Sovran.  The system I have is manufactured by Fireboy-Xintex.  They have redesigned the sensors since my boat was made.  On the top of the tanks the sensors can be found.  There will be a part number.  Contact Fireboy and they will send new sensors that are pre-calibrated .  Cost is about $100 each.  It is a 10 min install for each.  Here is the web site

Hope this helps
