'73 Vapor Canister

Does anyone have the vacuum schematics for the vapor canister? I know the one line that runs to the tank, the second to the PCV and the third to the carb but not sure where to attach it to the carb and how to link the PCV line from the carb to this one from the vapor canister.

thanks.

The line that goes straight to the carb hooks to ported vacuum and the pcv is connected with a tee.

Hi Jim,
Here are the connections from my 71 sb, q-jet. I believe your 73 is the same.
The diagram for running the hoses is in the AIM. Do you have one?
Regards,
Alan

No difference, regardless of carb brand. The 'control' line goes to a "ported" vacuum fitting on the carb and the "purge" line goes to the base of the carb so it can ingest the fumes. If there is a PCV valve involved, the "purge" line goes to a "T" connector which hooks with the PCV valve outlet, then goes to the base fitting on the carb.
