You'd think that if it was deposits on the wires of the sending unit, it would affect the entire gauge and not just the lower half? Granted, there is usually more gas in the lower half for longer periods that the upper half, but still?
So, is it the gauge that is faulty or the sending units?
This is definitely a common problem that doesn't seem to have a simple solution...
