Claim 13:
14. A method of using a fuel tank isolation valve, the method comprising:
providing a main valve body having a first port and a second port, the second port including a fitting defining a female receiving bore, the main valve body housing a vent solenoid in a main bore that is in fluid communication with the first port and the second port, the main valve body joined with a cover defining a cover cavity distal from the vent solenoid, the main valve body defining an airflow bypass orifice in fluid communication with the first port and with the second port;
placing a male connector extending outward from a fuel vapor canister in the female receiving bore, without any intervening hose disposed between the canister and the fitting;
engaging the fitting so that a clip, adjacent a spacer and an o-ring, converts from a release mode to a lock mode in which the clip engages the male connector to secure the fitting to the canister in a sealed configuration, the fitting and canister being secured directly to one another with the main valve body supported in a cantilevered manner by the male connector of the fuel vapor canister,
operating the vent solenoid in a closed mode in which fuel vapors are inhibited from moving from the first port to the second port through the main bore along a first path due to the vent solenoid occluding the first path; and
conveying fuel vapors from the first port, through the main bore, through the cover cavity, and then through the airflow bypass orifice, to the second port along a second path, while the vent solenoid is in the closed mode, and the fuel vapors are inhibited from moving from the first port to the second port through the vent solenoid and main bore along the first path due to the vent solenoid occluding the first path in the closed mode.
