Fig. 54 Charcoal canister less purge control valve
WITHOUT PURGE CONTROL VALVE
The carbon canister, Fig. 54, stores fuel vapors from the fuel tank and carburetor bowl until the engine is started. At this time, fuel vapors are
purged from the canister into the engine for combustion. Depending on application, either a 925ml or 1400ml canister is used.
On vehicles equipped with a dual canister system, two canisters are linked together and the second canister is used for ``spill over'' fuel vapors.
