EVAP System Overview

Some vehicles have an additional air filter installed on the Evaporative Emission (EVAP) canister.

Hose connections are secured with either spring type or clamp type clamps.

Hose clip pliers (VAS 6340) or (VAS 6362) are recommended for installing space saving clamps.

The connectors for the fuel, vacuum and ventilation lines are color coded. There is either a colored dot on the connector or the release button is the corresponding color.
