The gas gauge on my 81 Lebaron stopped working, I checked out the gauges by jumpering the temp sending unit and it moved so I am saying that the gauges are good. I think it is the gas tank sending unit. Do you have to remove the tank to replace it ? Also before I do that I was going to ground out the unit at the gas tank to see if I get movement. The car has been sitting and one day it worked and the next it did not. Any ideas ?
