Dad,
bench test (sitting on truck seat) was positive wire running to “e” side of gauge to positive battery post. Sender wire from “f” side to sender input (threaded bolt on sender). Ground was connected to round sender housing where bolts hold it onto tank to negative battery post. I also ran a wire with clips from gauge ground (back of gauge, NOT cluster) to negative battery terminal. (Where I misunderstood/jumped the gun was I thought I was supposed to assemble, one wire at a time and retest after each connection. Thinking that would identify any problems when something failed to work)

I will go back to “bench test” and figure out gauge/ cluster ground issue like Bartamos stated above.

Update: gauge is not making good contact with inside of cluster. I was able to slip a small shim to test connection this issue. With shim, I am getting full range of motion. Without, I only get Partial movement. (Cluster ear was used as ground.) Time to clean it up better, clean other “ears” off also.

If needed, Can I use a couple small drops of sodder inside cluster to close up any gaps? I know you stated small rivets previously.

Baby steps!
