Fuel tank venting arrangement

A fuel tank (22) for small internal combustion engines (18), the fuel tank formed of a pair of lower and upper housing members (26, 28) which are molded from a plastic material and are sealed to one another via heat welding, for example, to define the interior volume (34) of the fuel tank. The lower housing member (26) includes an integral vent tube (78) which extends substantially upwardly within the interior of the fuel tank and includes an open end (82). The upper housing member (28) includes an integral baffle wall (58) projecting downwardly therefrom which defines a baffle chamber (60) in which the upper end (82) of the vent tube is received. The lower housing member additionally includes an integral fitting (80) to which a vent conduit (86) is attached, the fitting in fluid communication with the vent tube. In use, fuel vapors are vented from the fuel tank by passing into the baffle chamber and thence into the open end of the vent tube and through the fitting and vent conduit to a carbon canister or other containment device.
