Abstract
A vehicle fuel filler tube collar includes an end wall and a side wall. The end wall has an inner surface and an outer surface with a first tube receiving surface extending from the inner surface to the outer surface. The tube receiving surface defines a tube receiving opening having a first diameter. The side wall extends from the end wall and has a first end that is contiguous with the end wall and a second end opposite the end wall. The side wall has an inner collar surface that defines a vent opening at the second end, and an outer collar surface. The vent opening at the second end has a second diameter larger than the first diameter.
