Having problems with your 1985 Chevrolet Caprice ?
Fuel gauge I have an erratic fuel gauge. How do I check to see whether it is the tank unit or the dash gauge?
It is not uncommon for GM fuel gauges to bounce up and down while the vehicle is moving. Especially on these older ones. Replacing the gauge or level sensor in the tank would only be a waste of money. It wont be the gauge though to answere your question.
