Vehicle fuel fill control systems may anticipate vehicle refueling events in order to control the timing of fuel tank depressurization sequences. In a first embodiment, a global positioning system (GPS) is utilized to anticipate the vehicle refueling event prior to initializing the depressurization sequence. In another embodiment, a camera system is utilized to anticipate the refueling event prior to initializing the depressurization sequence. In yet another embodiment, both the GPS and the camera system may be utilized to anticipate the refueling event. By anticipating refueling events, customer wait time for gaining refueling access may be reduced.

A separation nipple to separate a liquid from a vent inlet line into a filler pipe of a motor vehicle. The separation nipple has an inlet for connection to the vent inlet line, an outlet for connection to a vent outlet line, an opening for connection to an interior of the filler pipe, and a flap to close the opening. The flap has a main flap surface and a reflector flap surface which slopes relative to the main flap surface. The reflector flap surface is configured to form a reflector with the main flap surface when the flap is in an open position, the reflector being configured to deflect liquid passing through the opening in a direction of an end of the tank of the filler pipe. The opening is configured for closing by the main flap surface when the flap is in a closed position.

Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.
