I have a '63 with stock gas tank, sending unit, and gauge (as far as I know). The gas gauge reads 1/4 all the time. Any help on how to troubleshoot is much appreciated.
Please start your own post. I don't know if you can search because you are moderated. If you can search, there is more info on that issue in here than any other issue.
Glad to help if you can't search.
