Gas Gauge Needle Started Wobbling?

My 2004 2.7 regular cab(4wd) has been an amazing truck for 5 years without a single issue. So any issue that does pop up is a surprise. I filled up the truck with gas after the first snowstorm and cold snap in Minnesota. After about I noticed the gas gauge needle jumping around. Its continued to jump around maybe around a half inch of movement. Im wondering if the float is stuck? Not sure what could be the problem. Any ideas?

Mine does it when it's cold outside. I think alot of the '01-04 are prone to move around quite a bit.

 

Interesting. I can understand that but the truck lived in Montana for years and survived a cold winter in Northern MN last year without the issue. Wondering if the float could be loose?

 

my 02 has done this since new. mine is more noticeable on humid days. Anyhow i use the trip meter.

 

Mine's all over the place, I filled it yesterday and parked it. It read empty this morning until i drove a few blocks, then it came up above half for awhile.
Trip Odometer ftw.

Usually a bad float.

 

My 01 has the same problem occasionally. I believe it's a bad float. But I don't let it bother me because I use the trip odo.

 

Mine does it too, not necessarily a bad float. Sometime the contacts that the float actuates become dirty and the needle falls when it's on a dead spot(s).
