I am replacing the WEMA gauges on my 30T (1991) with a new Acugage system. I have removed the WEMA Holding Tank Gauge (Model HTG) and WEMA Water Tank Gauge (Model UPWR). Both gauges are operable and if anyone is interested I am pleased to give them for free to the first person who asks for one or both. Keep in mind I am offering only the gauges as I am leaving the WEMA sensors undisturbed in the tanks. I can be reached by e-mail through the Owner Directory.
