Here is something for you to read through, diagnostic help. I haven’t had time to read through totally, but just glancing through it looks like there are two different calibrations, is it possible that the wrong one was flashed into your truck by the dealer? Also just glanced at something that said the fuel gauge will default to empty when this DTC sets? I’ll have a little more time later this evening to read through everything.

In order from bottom to top.
