ABSTRACT:
A vapor handling system is provided to control fuel vapor in a vehicle fuel system to prevent the fuel vapor from escaping to the atmosphere during filling of the vehicle fuel tank. An on-board vacuum-actuated system is included for preventing overfilling of the tank by automatically triggering shut-off of fuel flow from a fuel-dispensing nozzle when the fuel tank is full. A control valve system is also included for protecting the canister from exposure to liquid fuel during an overfill condition which may be caused by a malfunction of a fuel-dispensing nozzle.
