Abstract: A capless fuel filler system has lower and upper sealing doors. The upper sealing door prevents water, water vapor, dust, etc. from entering into the space between the lower and upper doors. In prior systems with one sealing door a drain is provided to remove water (either directly entering or condensed water vapor), dust, or excess fuel drips from fueling just upstream of the lower door. By providing two sealing doors, water and dust cannot access the lower door. Although some fuel may puddle upstream of the lower door after a fueling event, the fuel is trapped, with no drain to the exterior, between lower and upper doors. If such fuel evaporates, it causes the lower door to open and vents the fuel vapors to the fuel tank, a desirable disposition for the vapors. The two sealing doors are contained in separate components to facilitate interchangeability and serviceability.
