I have a 76 and the fuel guage is all over the map. It seems to be sticking.
It usually will read right off the map - full, full, full. Then If I stop or decelerate suddenly it will go down to where the normal reading should be and I know how much gas I have. Sometimes it seems ok for awhile with proper reading and then it will start this again.
I did get a replacement fuel sender for this, but it looks like I have to drop the tank just to change fuel sending units and would like to be sure.
Any clues on what else I could check first?
TIA
PS. For anyone who was reading older posts I did get the new composite spring, shocks done and then recored the rad and replaced the rad support on it so that is all good to go now!
