Abstract:
An on-board refueling vapor recovery system includes a shutoff mechanism that closes a first vapor path between the fuel tank and the filler cup when liquid fuel in the tank reaches a predetermined level and a vent line closure that closes a second vapor path between the canister and the filler cup, wherein closure of the first vapor path and the second vapor path reduces pressure in the filler cup to induce shutoff of a fuel nozzle.
