Fuel Guage Mystery
On my 1974 450 SEL, when I start the car cold in the morning the fuel guage goes over to FULL. After 3-4 miles, it corrects back down to the proper level.
If this was a guage or ground problem I would expect it to always be non functional.
On the other end, if the float was "sunk" w/ a hole or whatever, I would expect it to always be sunk.
This happens consistenly, every day I drive it.
