Gas gauge bounces around above half tank

[HIGH BOWTIE]

Doesnt do it below half but over half it'll go crazy. It goes as far as the needle will go and back and fourth. Any ideas

Weird, my does the exact opposite. It's true until it gets below a half a tank, then it's all over the place.

Yea will I fill it up it take awhile to do it it's when it gets closer to between 3/4 and 1/2.

75% of the time (or better) it's the sender unit.

Best to also give the wiring a check and make sure the grounding points are good back by the tank...
