Fuel vapors from the fuel tank flow into the tube labeled ``Fuel Tank'' and are absorbed by the charcoal in the canister. The canister Fig. 68, is purged
when engine is running above idle speed. Vacuum is applied to the tube labeled ``Canister Purge'' to draw fresh air through bottom of canister. The air
mixes with vapor and mixture is drawn into intake manifold to be consumed during normal combustion.
