Yes, I was referring to the ground connection for the gauge itself. I just took a look at one to refresh my memory, and as I had thought, the gauge has a small metal contact on the back (right between the 2 studs) that simply touches against the metal cluster housing to connect the gauge to ground.

Another post I read said that the gauge itself is almost never the issue but I am almost certain I have ruled everything else out. Thank you for the suggestions.

You're welcome! Yes, it is quite rare (but not completely unheard of) for the gauge itself to be bad.
You can also check the continuity of the gauge's internal coils with an ohmmeter. With the gauge unplugged, measure between it's power terminal and it's ground contact. Also measure between the gauge's sending unit terminal and ground contact. If either one of them measures open circuit, the gauge is bad.
