Integrated fuel tank and vapor containment system

A fuel tank (15) for an engine (10) is disclosed that includes an air cleaner assembly (20) and an air-fuel mixing device (25). The fuel tank (15) includes a first tank portion (65) and a second tank portion (70) connected to the first tank portion (65) to define a fuel chamber (75). A canister (135) is at least partially formed as part of the second tank portion (70), and a first flow path (110) is at least partially formed as part of the first tank portion (65). The first flow path (110) provides fluid communication between the fuel chamber (75) and the canister (135). A second flow path (130) is at least partially formed as part of the second tank portion (70) to provide fluid communication between the canister (135) and at least one of the air-fuel mixing device (25) and the air cleaner assembly (20).
