I have a fuel gage that constantly bounces from full to empty, non stop. I have replaced the ground and still does the same. Sometimes it stops, but that is a rare occasion! Any suggestions, or do I need a new sender? Thanks

Crum! And here I've been wishing I had a fuel gauge... guess what they say about the grass over there...

Do you have a wiring diagram you could post?

Some designs of fuel gauges need a voltage control to provide a constant voltage regardless of what the charging system is doing. The wiring diagram would show this.

Can you easily remove the sending unit from the tank to examine it and also to see if the jumping from full to empty continues?

When you say you replaced the ground are you talking about the ground at the sender or at the gauge? Both could be important.

Fuel tank sending units tend to wear out, creating this problem.
Would help to know the following
Engine off key on, fuel guage jumps?
Different when engine running?
Worse or better when tractor moving?

This will help with what neexs to be looked at.
