To the list, Sorry for the delay but I just got to this. I had this system on my last boat. Nothing but problems starting year 3. Electrical problems and tank level indicating problems. Erratic, no indication, full when known to be empty, etc. I found the wires to be too small to splice and too hard to rewire. My electrical / electronic repair service had some experience and said it would cost me too much to repair, but that replacement was cheaper, and easier. Fireboy was willing to sell me a new system at a discount, but that was all. (Only 1 year warranty, as I remember!) in discussions with the manufacturer, his staff had told me they had many complaints and that as a result, they had a new system of a regular pickup tube with a nema gauge. The key difference was that they had plumbed a water wash-down for the pickup tube with the SUGGESTION that it be used once per month whether you were having problems or not. Installation was a snap, relatively speaking, and did the required wash-down as suggested. System worked without fail for the next 3+ years, and the admiral regained confidence that we could use the tank to about 3/4 full before having to look for a pump out station. Of course, YMMV.

I got the two-system gauge ( potable water and holding tank) and installed first the water system. Very easy. Works like a charm. In tank rod with no moving parts. Holding tank was a little more of a challenge. I have, like you, a fiberglass tank with very rough sides so snake River was out of the question. There was a funny system in there before, made by a company no longer in existance. The rods were attached to a 3 1/2 " PVC plug. I removed the rods from the plug and drilled a hole the size of the Xintex flanged sender. Put everything back together and connected the 2 wires. Works like a charm. A little pricey, but it's for a boat!!! Go to their website. Call them. They are very easy to talk to. And they are helpful and patient. No connections, just a happy customer. P.S. Looking forward to seeing a lot of listees at the Solomons Trawlerfest. We will have a get-together there. It is in the works. We are missing the super organizer Dennis Bruckel and Esther to do this tradition!
