I haven't understood what the FUEL terminal on the fuse panel is connected to. From your description, it sounds like the back of that terminal is connected to the sender terminal on the fuel gauge, and the tan wire from the sender plugs into the terminal on the front side.

Is that correct?

Yes the back of that terminal is the connection to the fuel gauge sender terminal. It is the tan wire to the no.4 terminal on the cluster plug. Here are the rest of the cluster connections for the gauge clusters.

The wires for the light cluster with warning lights is different but I think the FUEL sender wire still goes to no. 4 terminal.

Yes, the the FUEL terminal is connected to the tan wire. I had forgotten about that terminal. Grounding that helps isolate the dash harness along with the gauge from the rest of the circuit back to the sender.
Thanks for the help! VV
