can't fill the tank up

i've had my '08 for a few weeks now. every time i fill her up it stops pumping at like 3/4 of a tank. anything special you have to do on these trucks to actually get the tank to fill up all the way?

You may have a blocked vent hose. Mine fills up no problems. I'd take it to the dealer and have them look at it. (While you are at it, check to see you have the latest ECM flash - version AM for 08.)

Without a vent kit his truck should still show full after it clicks. It just wont sit at full for as long as if you had put int he 3-4 gallons after the click.

3/4 tank on a 34 gallon tank is a log of fuel that isnt going in the tank.

I would say check the vent hose or check your fuel sender.
