Gas gauge not working? I think I fixed it.

FYI. The other day I filled the tank and the needle is pegged so far right of full, I can not see it.
Will have to see if it comes down.
Put the gas can back in the trunk

After I shut off the car today, I stopped to see if the needle was pegged or stuck at F. I saw it work its way to Empty, thus the needle was not stuck or broken off
