Abstract: A collection and disposal system for intercepting fuel vapor, liquid fuel, and water accumulating at the filler neck compartment of a motor vehicle. The system includes a suction fan, a plurality of conduits communicating between the filler neck compartment and the suction fan, a collector for liquids accumulating in the filler neck compartment, and an electrical control system. The control system includes a switch which operates the suction fan when the filler neck compartment door is open. The suction fan draws vapors from the filler neck compartment through the conduits for disposal. Vapors may be conducted to the emissions control system, in particular the charcoal canister for trapping vapors, a suitable point of the engine such as the intake manifold, carburetor, or throttle body, or may be vented to the open atmosphere. The collector of liquids has a flapper valve which discharges liquids when a predetermined volume is collected. A buzzer is arranged to annunciate operation of the suction fan.
