why is my gas gauge erratic

What is your question?

My gage is all over , full empty half 1/4 3/4 even on a full tank it goes back and forth never accurate I replaced the fuel pump and sending unit and apparently that was not the problem Because I still have the same issue , is there something else ,to look into thank you

What makes this problem better or worse?

happens every day all the time

How long has your 2009 Ford Escape had this problem?
