ABSTRACT:
In accordance with the present invention, there is provided a filling and venting system for a fuel tank which includes a canister having a fill section and a vent section defined therein. The fill section including a fuel inlet portion for the introduction of fuel thereinto and a fuel outlet portion configured to be attached to a fuel tank for directing fuel thereinto. The vent section includes a vapor outlet port configured to be attached to a vent and a vapor inlet port configured to be attached to the fuel tank to permit vapor to pass from the fuel tank, through the canister and to the vent. The vapor inlet port is configured to project into the fuel tank to a level below a level at which the fuel outlet port enters the fuel tank. A partition assembly includes a wall separating the fill section and the vent section. The wall includes an opening defined therein which permits fluid to flow therethrough. The partition assembly further includes a floatable sealing member which is disposed so as to cover the opening in the wall to prevent fluid flow therethrough when a level of liquid in the canister is below a predetermined value and to uncover the opening when the level of liquid is above the predetermined value.
