Mine was in the glove box.I heard there was a fuel filler funnel that came with the truck, is this confirmed? If so, worth going back to the dealer and getting one?

Do you have a gas cap? If not, then there is a second door flap behind the spring loaded door you put the nozzle in.Hmm mines a diesel and doesn't have a flap that I noticed. I also don't have the adapter..at least I haven't found one yet lol
I found mine in a bag with a GM part number on the bag in the compartment under the left rear flip up seat cushion.When new, they are put in the glovebox in a bag with a GM part number on the bag.
