Have had a strange problem with the fuel sender/gauge system for some time. As we are in the process of replacing the tank I was going to replace the sender unit, however as we had the tank out we had an ohm test done on the sender with it removed from the tank and it seems to be working just fine. The sender is not that old and is of the floating donut over a stainless rod type, not the lever type.
So the system works just fine much of the time and then for some reason will shut down and the needle on the gauge drops to indicate no fuel and will stay there. It never bounces around like it may if you had a fast intermittent bad connection; it just goes dead. There is a good chance that the next time you start up the boat that it will work just fine, especially if it has had a rest but not always and some times it will start on an immediate motor restart - but far less often and once it goes dead it is usually dead for a while. It never spontaneously starts up again with the boat running - it always needs a power off and on/motor restart, usually on a different day to start working again.
I hate intermittent problems. It acts almost as if an IC chip gets over heated and then shuts down and then works just fine at another time. It works enough of the time that it is still useful but still very frustrating. We don’t go that far and I know the boat very well so there is no chance we will ever run out of gas and in fact it is never allowed to drop below 60% full as we like the weight on the keel line for added stability and the security of a large fuel reserve. Don't really need a gauge, just top up the tank no less frequent than after every third fishing trip and the tank will stay above 60 % full.
Anyone got any ideas or suggestions ???
