Fuel vapor emissions from a fuel tank directed to a canister containing adsorbent are minimized by an intermediate condenser and conduit configuration. Condensing and cooling fuel vapor emissions allows a reduction in canister capacity, where the canister can still meet and accommodate refueling and/or diurnal emissions control requirements. Pressurized and unpressurized fuel tanks for various vehicles, including vehicles with an internal combustion engine and hybrid electric vehicles, can be configured with the present fuel vapor recovery systems.
