Could have blown up both the car and the house.

Yes, there is a tube, it comes out on top of the filler tube, 1/4" or so, then a little rubber hose, and a new tube that goes up around where the left trunk lid hinge is, and then finds it's way down and into the gas tank where the filler tube goes in. So, I assume that is connected to the tank too, to let air out of the tank when fillling. Or is it something I am missing here ?
