Fluctuating Fuel Gauge

Fluctuating Fuel Gauge
Hello All,
I am back with another issue with my 09 Tahoe, this time it's a problem with the fuel gauge. Over the last couple of days I have noticed that the gauge fluctuates - today I started the car and had a 1/4 of a tank which I think was accurate based on when my last fill up was, I drove about 15 miles to run some errands and while sitting in a parking lot I observed the gauge gradually move up to above 1/2 and then back down. It continued to act like this until I started driving again and it stopped moving around. It pretty much moves around any time I stop and the fuel range in the DIC goes up and down as well. Sometimes it goes up and down quickly and other times slowly. If I stop and restart the car the gauge returns to what I believe is the right level.
Any ideas what could be going on here? Thanks!

Yes and no. You can replace the fuel pump, without changing the fuel sender. Since dropping a gas tank without
a hoist or lift is a bear, I'd do both at once. Make sure your fuel is very low, if you do. Makes it much easier to do.
