Exhaust Emissions System - EVAP: Description
Fuel evaporation system is designed to prevent fuel vapors from being emitted into the atmosphere. System consists of a non-vented fuel tank filler cap, an expansion chamber, an activated charcoal canister, and a series of vent lines which interconnect the components between the fuel tank and air cleaner. On air-cooled models, a pressure line, used to purge the system, is connected between the engine blower assembly and the charcoal canister.
