You'll find lots of good people on here to help you. There's also a Facebook group now, too. https://www.facebook.com/groups/180207095371053/about
I see you've already put a wanted-post in the Traders Market section so that's covered, too.
Do you have a hard copy of the FMC Parts & Service manuals? If not you'll find most of their contents here: http://www.fmcmotorcoach.com/
I'm not too hot with the tank level gauges. I do know that if scum gets built up inside the tanks it can effect continuity readings. You might try the 'douche the tanks with bleach thing' as (IMHO) it's a good idea to disinfect the entire water system regardless. Bleach can/will usually remove any build-up coatings inside any of the tanks. First check there's no hidden water filter hiding in a cabinet somewhere in case there's a foosty old cartridge in there. I usually put about 2-3 cups of bleach (5% chlorox) in a gallon or two of water then pour that into the potable water tank(s) then fill them with water. Once full, run all the faucets for a few seconds each, then top off the water tanks again. Fill your grey & black water tanks also with the same solution then take the coach out for a good spin around the block a few times. Do a lot of swerving around and hammering on the brakes suddenly - neighbours will think you're drunk but don't worry - to get all that solution sloshing around in them tanks. Then let the coach sit over night. Next day drain & refill the potable water tanks a couple of times and that will rid the tanks of the chlorine taste and give the system a good flush. This may not solve your gauge issue but you'll have a clean safe water system. You might also consider a water filter system if there's not one there already.
Good luck and enjoy your coach!
