EVAP Emission Canister: Installation

Place the EVAP emissions canister in the pocket on the top fuel tank. Make sure that the canister vent hose is positioned towards the middle of the fuel tank.
NOTE: If a replacement canister is being installed, make sure that the vent hose is installed on the canister prior to installation on the fuel tank. Orient the molded vent hose on the canister so that when it is installed on the fuel tank the "S" bend will be pointing down.
Install the canister retainer clip to the fuel tank, assuring that the clip is over the lower flange of the canister before "snapping" the clip into the locked position.
