A filler neck closure assembly (20) includes a housing (74) formed to include a passage (77), a tank pressure control assembly (84) in passage (77), and an outer shell (44) coupled to housing (74). Closure assembly (20) includes a sleeve (185) that reinforces housing (74) and shields tank pressure control assembly (84). Closure assembly (20) also includes a sealing gasket (192) and a foam ring (210) between housing (74) and a side wall (46) of outer shell (44) leakage of fuel vapor therebetween. Outer shell (44) includes frangible tabs (260) that break away from the rest of outer shell (44) in a controlled manner when outer shell (44) is subjected to an impact during a vehicle crash. Outer shell (44) is formed to include a fluid drain (421) and closure assembly (20) includes a float (425) that closes fluid drain (421) and that moves to open fluid drain (421) to allow accumulated fluid to drain out of outer shell (44).

1. A filler neck closure assembly for a vehicle fuel tank filler neck, the closure assembly comprisinga housing formed to include a nozzle-receiving passage and adapted to couple to the filler neck, the housing including a 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 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 having an outer wall surrounding at least a portion of the cylindrical side wall of the housing and a nozzle-guiding surface extending from the outer wall and defining a central opening in fluid communication with the nozzle-receiving passage, and a sleeve surrounding the cylindrical side wall to reinforce the cylindrical side wall and to shield the portion of the tank pressure control assembly surrounded by the cylindrical side wall, the sleeve being positioned to lie between the outer shell and the housing and at least a portion of the sleeve being positioned to lie between the outer wall and nozzle-guiding surface of the outer shell.
