Abstract
A capless fuel system having an elongated tubular and cylindrical housing open at each end and in which the housing defines a first and a second longitudinally spaced fluid ports. A first flapper valve is associated with the first fluid port and a second flapper valve is associated with the second fluid port. A pair of diametrically opposed latches pivotally mounted to the housing adjacent the second fluid port retain the second flapper valve in a closed position until a fuel nozzle of a predetermined size is inserted towards the second port. The fuel nozzle engages camless surfaces which pivot the latches away from the second flapper valve allowing the fuel filling nozzle to pass through the second port.
