The fluid levels indicator on my 2000 356 operates normally for the freshwater and waste water channels, but very erratically on the diesel fuel channel, sometimes reading full, other times empty, and many in between (while the fuel tank remains half full). I checked the connections on the wiring harness and all are good. I decoupled and recoupled the connectors--no change. I pulled off the indicator unit and electronics and all looks in good condition. I disconnected the wiring harness connector and reconnected it--no change. I then spoke with Snake River and they recommended a new fuel sensor, which I bought, installed, and it worked beautifully for one day. I left for a month and when I returned to the boat it read just as erratic as the old one, while the water channels are still good.I am at a loss. Any experience with that problem? Any fixes?Thanks allIvan BekeyS/V VictoriaH356 #157
