The earth wire if connected to the sender base by the bolts. You need the wire/ terminal to have direct contact with the sender base. ie no washers between the wire and the sender base.
Hope this helps and you can be out enjoying your ride.

There are no fiber or nylon washers, but there is some sort of thin gasket sealer under the metal washers and on the bolt threads. This bothered me, so I am pretty sure I checked the continuity from the installed sender base to the tank with my meter. Even so, I will try this. It will be a few days before I can get back to it.

Thanks for your help.
