ABSTRACT:
The fuel storage system includes a control valve having a valve body which is movable along the inner circumferential wall surface of a filler pipe and which defines a passage isolated from the inner space of the filler pipe. A fuel tank and a canister communicate with each other via a main vapor line. When a fuel cap is attached to the filler port of the filler pipe, the valve body of the control valve is pushed by the fuel cap to be shifted away from the filler port, whereby a first sub-vapor line extending between the fuel tank and the control valve via the passage defined by the valve body is communicated to a second sub-vapor line extending between the control valve and the middle part of the main vapor line, permitting evaporative fuel gas to be introduced from the fuel tank into the canister. When a feed nozzle is inserted into the filler pipe to open a lid disposed therein, the valve body is shifted toward the filler port to allow the second sub-vapor line to communicate to the inner space of the filler pipe, to permit evaporative fuel gas to be introduced from the fuel tank into the filler pipe, preventing inflow of the outside air through the filler port attributed to drop in the internal pressure of the filler pipe, and generation of fresh evaporative fuel gas. Lowering in the refueling performance and over-refueling can be also prevented.
