Fuel gauge is way way past full / 1995 Tahoe

[Deepair3]

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?

Based of what you said about filling half way and said full and then filling and read over full, I say the sending unit is failing/failed.

Can get just the sending unit. 2 door: 25027414 or 25178862....Or aftermarket

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.
