A fuel tank vent apparatus comprises a housing. The housing comprises inner and outer sleeves providing a fuel vapor transfer passageway therebetween so that liquid fuel entrained in fuel vapor is shed therefrom as fuel vapor flows from a fuel vapor transfer port formed in the outer sleeve through the fuel vapor transfer passageway to a fuel vapor inlet port formed in the inner sleeve to produce a flow of demoisturized fuel vapor for discharge from the housing.
