Zusammenfassung:	A vapor recovery system between a fuel tank and an engine intake manifold includes a T-fitting to provide a vacuum break. The first and second ends of the T-fitting are connected in line with a vapor recovery hose, and the third end draws outside air into the T-fitting and may have a filter attached thereto. A flow restrictor also is provided in the first end of the T-fitting, to limit the flow of vapor from the fuel tank and maintain adequate vapor space in the tank.
