Seal for filler neck closure assembly

A filler neck closure assembly for a vehicle fuel tank filler neck, the closure assembly comprising

• a housing formed to include a nozzle-receiving passage and adapted to couple to the filler neck, the housing including a first cylindrical side wall,
• a tank pressure control assembly coupled to the housing, at least a portion of the tank pressure control assembly being surrounded by the first cylindrical side wall, the tank pressure control assembly normally closing the nozzle-receiving passage and being operable to open the nozzle-receiving passage,
• an outer shell coupled to the housing, the outer shell including a second side wall surrounding the first cylindrical wall side wall so that an annular space is defined between the first cylindrical side wall and the second side wall, and
• a ring of absorbent material positioned to lie in the annular space between the first cylindrical side wall and the second side wall, the absorbent material being configured to absorb axial and radial impacts applied to the outer shell.

A filler neck closure assembly for a vehicle fuel tank filler neck, the closure assembly comprising

• a housing formed to include a nozzle-receiving passage and including a first portion adapted to couple to the filler neck, the first portion being made of a conductive grounding material,
• a plate supported by the housing and formed to include a nozzle-receiving opening, the plate being adapted so that a fuel-dispensing pump nozzle is insertable through the nozzle-receiving opening into the nozzle-receiving passage,
• a door coupled to the plate and movable between a first position closing the nozzle-receiving opening and a second position opening the nozzle-receiving opening, the door being made of a conductive grounding material, and
• an electrical coupler contacting the door and contacting the first portion to provide a grounding path for static electricity associated with the pump nozzle when contact is made between the pump nozzle and the door during insertion of the pump nozzle through the nozzle-receiving opening.

• a housing formed to include a nozzle-receiving passage and adapted to be coupled to the filler neck,
• a tank pressure control assembly coupled to the housing, the tank pressure control assembly normally closing the nozzle-receiving passage and being operable to open the nozzle-receiving passage,
• an outer shell coupled to the housing and formed to include a nozzle-receiving opening, the outer shell including an accumulation area in which liquid accumulates, the outer shell being formed to include a drain communicating with the accumulation area, and
• a float retained in the accumulation area, the float being movable between a first position closing the drain and a second position opening the drain so that liquid flows from the accumulation area through the drain and out of the filler neck closure assembly.

• a plate supported by the housing and formed to include a nozzle-receiving opening, the plate being adapted so that a fuel-dispensing pump nozzle is insertable through the nozzle-receiving opening into the nozzle-receiving passage,
• a door coupled to the plate and pivotable about an axis between a first position closing the nozzle-receiving opening and a second position opening the nozzle-receiving opening, and
• a standoff rib appended to the door, the standoff rib being positioned to engage the housing to limit the amount by which the door pivots during insertion of the fuel-dispensing pump nozzle through the nozzle-receiving opening upon movement of the door to the second position and to disengage the housing upon movement of the door away from the second position toward the first position.
