Howdy!
Here's an interesting new phenomenon in my truck (a 1954 3100) that I'm trying to figure out. The gas gauge reads totally full, even though I know its only git about 3/4 a tank of gas. When I start driving down the road, the needle begins jumping all over the place, but always goes back to "full". This is a new issue, the gas guage has worked normally for many years before this. What think ye?
