ABSTRACT:
A vapor handling system is provided that uses negative pressure created during discharge of liquid fuel from a fuel-dispensing nozzle into a filler tube to actuate a remotely situated vapor venting valve. Actuation of the vapor venting valve permits fuel vapor in the fuel tank connected to the filler tube to be communicated to a vapor treatment canister or the like.
