Abstract
A vehicle fuel vapor recovery system includes a compartment wall structure, a fuel filler tube and an air vent chamber structure. The compartment wall structure has a tube receiving opening and a vent opening. The fuel filler tube has a fuel receiving end located within the fuel filler compartment and a fuel tank attachment end located outside of the fuel filler compartment. The air vent chamber structure has a first wall located outside of the fuel filler compartment and a second wall extending from the first wall to an outer surface of the fuel filler tube. The first wall, the second wall, the fuel filler compartment wall structure, and the fuel filler tube cooperate to define an air vent chamber.
