A full tank creates higher resistance that makes the gauge read full, right? So if there's failing ground, the gauge would read full?
My thinking is that, at 51 years old, the ground strap might be the culprit. In order to test that, I could access the gauge wire under the dash and look for resistance of more than 88 ohms with a full tank?
