Patent ID: 7610905

Claim:
A fuel reservoir assembly comprising: (a) a fuel reservoir having a quantity of fuel and a quantity of fuel vapor, said fuel reservoir comprising; an enclosure with an exterior wall; and an internal holding volume with a vapor region having said quantity of fuel vapor; (b) a body securely mounted to said exterior wall, comprising; a fuel inlet; and a fuel outlet in communication with said internal holding volume; (c) a center fuel flow axis defined along the length of said body from said fuel inlet to said fuel outlet; (d) a housing disposed around a circumference of said body and secured to said exterior wall, comprising; at least one atmospheric air opening; and at least one vapor emission inlet for communication with said vapor region; and a hydrocarbon filter disposed between said at least one atmospheric air opening and said at least one vapor emission inlet and passively filtering said quantity of fuel vapor emissions within said vapor region, said hydrocarbon filter being purged due to draw of fuel from said fuel reservoir; and (e) an evaporative emission line coupling said housing to said fuel reservoir through said exterior wall; wherein said housing comprises a hydrocarbon filter purge path for air and said quantity of fuel vapor to flow in said at least one atmospheric air opening, across said hydrocarbon filter, substantially along a plane that is not parallel to said center fuel flow axis, and through said at least one vapor emission inlet.
