I didn't see any individual replacement parts either in the WM > catalog or on the Sealand website. Unfortunately SeaLand doesn't offer any of the components for their tank level monitors, only total replacement. My advice: replace the sender with one of the Profile system senders that goes on the outside of the tank. It should work with your wiring and panel. http://ferriellosales.com/default.php -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/boat_odors/
