A fuel vapor filter (10) for use with a fuel nozzle (22) for filtering fuel-entrained vapor (60) displaced from a fuel tank and a fuel tank fill tube (18) during refueling. The filter (10) comprises a housing (12) containing a filter (14). An external boot (16) encloses the fill tube (18) during refueling. A splash shield (46) prevents splashing of liquid fuel on the filter housing (12). The filter (10) of the present invention protects people and the environment by preventing the escape of fuel-entrained vapor from the fuel tank during refueling.

A portable filter to enable sealable mating of a fuel delivery nozzle with a fuel tank fill tube during refueling to prevent the passing of fuel vapors to the atmosphere, the filter comprising: a housing having a central opening sized to be slidably engaged with a fuel delivery nozzle; one or more vents formed in said housing to enable fluid communication between an interior of said housing and the exterior of said housing; means for sealably engaging said housing with the open end of a fuel tank fill tube; a filter means positioned in said housing such that as fuel is delivered to the fuel tank, displaced gas exiting through the fill tube passes through said filter means to remove entrained fuel vapor prior to venting to the atmosphere; and means for deflecting liquid away from said filter means, said deflecting means being positioned between said filter means and said engaging means to deflect liquid fuel splashing out of the fuel tank fill tube back into the fuel tank fill tube wherein said deflecting means comprises a flange having a first end connected to said central opening and a second unconnected end projecting from said central opening to a position adjacent said engaging means.
