A fuel tank isolation valve is provided having a main valve body including a fuel tank port and a canister port, a main bore, and an actuator selectively operable to allow or inhibit vented fuel vapors to move from the first port to the second port along a first path. The body can define an airflow bypass orifice that allows vapors to move from the first port, through the main bore, to the second port along a second path, while the actuator is in the closed mode inhibiting vapors from moving along the first path. This flow through the orifice can equalize pressure in a fuel tank and the canister during a purging operation on the canister. The valve can include a fitting that directly couples the valve to the canister without any intermediate hoses, in a cantilevered manner. A related method of use is provided.
