Hey Dave, apologies I didn't get a chance to respond to your PM.
As Robin suggested i think you need to try to isolate the problem.
The circular connectors themselves can be a source of problems with corrosion or tarnishing on the terminals. You can remove them by popping out the centre pink retainer in the connector.
I have a variable resistor which I use for testing in the same way that Robin suggested, you can do this at the bulkhead side of the circular connector and also at the gauge cluster connector to try to narrow down the problem. Have you tried to continuity check from the gauge cluster connector to the sender connector? Symptoms are of an open circuit or high resistance of a damaged or burnt wire.
