I followed the diagram on the hood and it has pictures of parts not on the car such as the Canister Control Valve that has the vacuum ports shown on the diagram. I went to the Auto Zone site and the confusing part is they have the valve on the schematic but not on location or parts list. There is a valve next to the canister on my car but it only has ports for small hoses not for the lg. hose off the "T" port on the carb. Any help?
