Abstract
A capless filler neck creates a vapor-tight closure for a fuel system using a spring-loaded door and a latch structure that anchors the door to create a vapor-tight seal. The filler neck includes a spring that biases the door shut and a wedge arrangement that acts as the latching structure. The wedge arrangement includes a movable plate that selectively engages with the door to pull the door shut with sufficient force to form and maintain the vapor-tight seal.
