can you read the signs at the gas station? you know, the one that says "please turn off vehicle before pumping gas".
i'm pretty sure it says the same thing in the owners manual.

Over on the Ford diesel site, (my daily drive is a Ford Superduty), there was a discussion of how the fuel gauge works. The Superduty fuel gauge does exactly the same thing. If the F150 fuel gauge follows the same logic, (I do not know but would guess that it does), then what you are seeing is normal.

its called a slosh module, so that the fuel when you have a half a tank or so, wont slosh around and make the needle move. On your older truck that the needle would move up while filling, you probably have also noticed when it got low in fuel it is hard to tell where the needle's supposed to be(especially if you drive it rough). So the slosh module is constantly taking an average of where the float is and adjusting the needle to the average.
Also, filling with the truck running wont cause a check engine light because the only time the evap monitor tests are run are under very strict conditions (above 45mph after so many minutes .........). So the evap tests cant ever actually run when you are at a stop.
