Welcome to the site. I will move this thread to the Cummins section,

What is the exact problem you are seeing? I have a 2012 2500 gas and when I fill the tank up and drive 15 miles, I am already below the full mark. When I fill it up it just touches full and the needle does not travel past full.

 

Phil, Some times when you fill up the guage will go to full other times it does not move and the low fuel light comes on...On vacation drove on rough gravel roads thing maybe a loose connection...no difference. It's even come up to half full for a while when the tank is halh full but usally it hangs out around quarter tank...Don
