If you've got a warranty on the truck, they are on the hook. I believe that fuel cap is a federal emissions thing, so they can't dodge the fact that it is 'critical' (am I wrong on that?). You may have to threaten taking them to small claims court for the cost of getting it repaired somewhere else..... maybe THAT will motivate them.
This is not a "can't be fixed" issue, and it's not a superficial thing like cosmetics. They need to make it right.... try calling your state's consumer affairs office to see what they have to say about the dealer failing to repair a mandated federal emissions failure. What kind of warranty do you have anyway? The dealer shouldn't be concerned unless he's the underwriter.
Lastly, don't the emissions elements of our warranty have some ridiculously long coverage period??? (Speed?.... I think you know this one?)
