An apparatus for controlling discharge of fuel vapor from within a vehicle fuel tank, which apparatus includes at least a primary and auxiliary liquid separating chamber positioned above a float chamber below a valve outlet. The apparatus includes at least one baffle arranged to intercept and direct filtered fuel droplets from the vapor flow and return the liquid fuel to the fuel tank. The primary and auxiliary liquid separation chambers and associated baffle are positioned to facilitate flow of fuel vapor from the tank yet return liquid fuel to the tank.

1. An apparatus for controlling discharge of fuel vapor from within a vehicle fuel tank, the apparatus comprisinga valve container adapted to be installed in a fuel tank and formed to include an inlet in communication with the fuel tank, an outlet, and a main chamber defined therebetween, a float valve assembly disposed in said main chamber and formed for movement between an open position allowing flow of fuel vapor through the outlet and a closed position preventing flow of at least fuel vapor through the outlet, said float valve assembly controllably providing communication between said inlet and outlet, a primary liquid separation chamber in said main chamber defined between said float valve assembly and said outlet, an auxiliary liquid separation chamber in said main chamber defined between said primary liquid separation chamber and said outlet, said outlet defines a flow path from a second valve to said apparatus and from said apparatus to a vapor control canister, and a baffle retained in said container between said primary liquid separation chamber and said auxiliary liquid separation chamber, said baffle includes at least one aperture therein providing communication between said auxiliary liquid separation chamber and said primary liquid separation chamber.
