You don't want to have it go from the Charcoal canister to a vacuum source. The purge valve will direct it into the intake via either the vent or a TEE. A vacuum line directly to the cannister purge would cause the cannister to flood.

If you have an aftermarket air cleaner on the base you may have a capped vent which you could use. Just be aware a backfire could cause an explosion if a check valve isn't used.

Vile: Because there are several different styles of canisters and because I'm a little dense, I'd like you to look at the way I have it hooked up.  You are saying the the purge line I have tee'd in with PCV should be vented to the air cleaner.  I would think the vent to the right would prevent vacuum from pulling liquid fuel into the canister.  No?  Based on the pics I took before pulling apart my 305, this is how it was hooked up originally (except the vent was going to the air cleaner).



This is the go-by I used:
