To prevent gasoline vapors from being vented into the atmosphere, an evaporative emission system is utilized to capture the vapors and store them in a charcoal filled canister.
SERVICING THE EMISSION CANISTER
Since the canister is purged of vapors when the engine is operating, no real maintenance is required. However, the canister should be visually inspected for cracks, loose connections or other potential problems. Replacement is simply a matter of disconnecting the hoses, loosening the mount and replacing the canister.
