All of the other gauges read right. Well the Oil pressure bounces around before she settles. After this girl sat for two years, I drained what was left of the gas and then filled her halfway and noticed the gauge was on full. the next time I filled it all the ay up and it is way past full. Any suggestions?

I was hoping that wasn't the case. But, I will add it to the list to fix over the Winter. Thanks for your help!
Yea, the way you described is a classic example of the resistance in the sending unit circuitry going bad or is bad. You may find something else as you take it apart but I believe the gauge is ok and is just reacting to a bad sending unit signal from the tank.
