Fuel Gauge Operation/Troubleshooting

Is the fuel gauge for each fuel tank (Rinker 330) powered by the appropriate key, or does either key power both fuel gauges?

I'm prepping my 330 for sale and the port fuel gauge doesn't work.  The starboard fuel gauge works fine but it works with either the port or starboard key in the on position.  None of the other gauges do this (volts, etc).  Is this normal?

I know my port sending unit is working fine, so I'm wondering if the gauge itself is broken but I don't understand why the starboard fuel gauge reads when only the port key is on.  If this is normal behavior, I assume the gauge is the problem.
