EVAP Canister

The EVAP canister, filled with charcoal pellets, stores the fuel vapors from the fuel tank. Vacuum is pulled from the fuel tank through the vapor pipe (2). Fresh air (3) is mixed with the vapors and pulled to the intake manifold from the canister through the purge line (1). The engine vacuum purges the EVAP canister during normal driving.

IMPORTANT: Use the J 41413 [1][2]EVAP pressure/purge diagnostic station in order to provide a clean, dry, low pressure gas source. Do not substitute any other pressurized gas source. Damage may result to the EVAP system.
