Erratic fuel gauge

Video not available.

Google gauge servos. Pretty common failure on these trucks. There are a number of companies online & on Ebay who did them.
 
It is just recalculating the range for the current conditions, if you notice the gauge is going up.


On mine it goes down.
 
It just started doing this. It went from saying I had low fuel on my drive home. Once I pulled up in my driveway. It decided to start increasing.
 
Try some fuel system cleaner it see if the float in the tank is sticking.
