It is a 1973 with 3 lines. I have the bowl vent capped since this carb doesn't have that provision.What year is the car? The charcoal canisters either had one or two lines coming off it to the engine/carb. If it's only one, then the other is capped on the canister.
Please consider replacing that rubber fuel line with a metal line!
The canister connects to the carburetor float bowl vent. The 1406 does not have a nipple for the canister to connect to, so you will have to either leave it off, or you can connect it to a nipple on the air cleaner assembly.
This is the purge connection though?. I understand the bowl vent, but my MP air cleaner doesn't have a nipple provision.
Which car is this on? Do you have an FSM for it? That would tell you exactly which lines go where.
It's a '73 Dart Sport but no longer stock. I believe the purge was to connect to a port just above the throttle plate. I have to the vac advance connected to the timed port. The other port on the carb is manifold vacuum. Do I connect the vacuum advance to full vacuum and connect the purge canister port to the timed vacuum port on the carb?

I am ordering the Edelbrock metal banjo line. I was not able to fabricate a steel line to my satisfaction.

First, your 1406 carb does not have an external bowl vent. Most carbs during the charcoal canister era did. This external bowl vent was fitting coming out of the top of the fuel bowl usually and it was connected to the appropriate fitting on the charcoal canister. I believe this fitting was often labeled "carb" but you'd need to check the allpar article to be sure. Again, your carb doesn't have an external bowl vent, so if you have this fitting on your charcoal canister just cap it off.
The purge port on the charcoal canister from the factory is supposed to hook to the purge port on your carb. The purge port on the carb is a port similar to your ported vacuum port but the fitting is a larger diameter. The purge fitting only has vacuum off-idle, similar to a ported/timed vacuum port. Your 1406 carb does not have this port. In order to make your charcoal canister function properly, with your air cleaner setup, you will need to do the following:
First, you need to see if your charcoal canister has a purge valve built into it. It usually looks like a cylinder on top of the canister.
If it does have this valve all you need to do a tee a line from that purge port to the PCV line.
If it does not have that valve you need to purchase a separate one NAPA Echlin #2-28011. Run a hose from the purge port on the canister, to the purge valve, and then tee the purge valve into the PCV line. The small fitting on the top of the purge valve you need to tee into the vacuum advance line.
Yes, definitely put a fuel filter there.NOS canister- should I install small engine fuel filter on the purge outlet to prevent charcoal to dump in the pvc line? If it should start to degrade?
