my fuel gauge was working fine and then somehow I left my key on for about a week or two and the gauge now pegs below empty when I turn the key on and power goes to the gauge. I am thinking maybe the sending unit needs to be replaced. has this happened to anyone before?
I'm having the opposite problem. Mine starboard gauge pegs to full (wish it was at @4.95gal on the lake.) I found some info on the Teleflex website (I think sea ray gauges are made by Teleflex) which may help you troubleshoot. It could be a simple as a disconnected wire or bad connection in your case.
