At the fuel filler neck, just beyobd the truck exteriot the filler hose is coupled with a 1/4" breather tube. It appears the hose is missing. Therefore every time I fill up the truck diesel runs out onto the ground. Where does the missing breather hose go to? What is the part #

If you look under the truck, there should be the steel down pipe (filler tube) and a breather that attaches to the side of it. Check to see if that has come apart.

PLEASE NOTE: This is an emissions system component that is covered 100% by the manufacturer for a minimum of 5 years or 50K miles. You are completely under warranty and the vehicle should be returned to a dealer for proper (and free) repairs.

Let me know if they give you a hard time.
