Abstract
A compartment wall structure defines a fuel filler compartment that includes a tube receiving opening and a vent opening. A fuel receiving end of a fuel filler tube is located at the tube receiving opening of the fuel filler compartment. A fuel tank attachment end thereof is located outside the fuel filler compartment and is spaced apart from the compartment wall structure. An air vent structure is in fluid communication with the vent opening. The air vent structure defines a chamber opening connected via a vent line to a fuel vapor filter canister. Vapor from the fuel filler compartment is vented to the fuel vapor filter canister through the chamber opening. The air vent structure has a screen at the chamber opening to prevent entry of objects, such as, for example, insects and/or debris through the chamber opening.
