Also measure at the radio ground. You should have 0 volts at both locations. If you have more than .1-.2 volts you have a poor ground somewhere. Start at the battery cable first. If everything is OK and you have the radio wired correctly then the problem is probably in the radio.
For the gas gauge remove the green/black wire from the sending unit. Temporarily connect it to ground with ignition on, if the gauge is good it will slowly go to full, providing you are using a good ground. If it doesn't move check for 12 volts on the disconnected G/B wire. If no voltage there check for 12 volts on the green wire attached to the gauge. I don't think your two problems are related since you say everything else works.

Clifton I forgot to say I used two different radios and got the same result
