ABSTRACT:
In a fill tube of a vehicle fuel tank, an inlet forming device for receiving the nozzle of an associated fuel pump for filling the fuel tank and including an apertured seal member adapted to encircle the fuel nozzle to prevent fuel vapors from escaping therebetween. The device includes at least one vent opening which is normally blocked by an overlying edge portion of the seal member, but which is movable from its overlying position outward to vent fuel tank pressure. The overlying portion of the seal is normally biased to a closed position by the natural resiliency of an adjacent open celled foamed plastic material which also acts as a filter when the overlying edge portion of the seal is moved to a more open vent position.
