Abstract
A vehicle fuel system includes a fuel vapor recovery canister containing a carbon bed configured to capture hydrocarbon material associated with fuel vapor discharged from the fuel tank into the canister. A purge vacuum is applied to the canister to draw fuel vapor carrying reclaimed hydrocarbon material from the canister into an intake manifold coupled to an engine so that the reclaimed hydrocarbon material can be burned in the engine.
