3.8 Evaporation Control System

The evaporative control system is shown below (Fig. 10). The 380cc carbon canister must be
present and connected as shown to meet CARB evaporative emission standards. Use the OEM
replacement hose, if possible. This grade of hose is commonly available at au

to part stores as “fuel

hose”, if the OEM replacement hose is unavailable.
