Evaporative Canister Carb connection
So I have the stock evaporative emissions canister and all factory lines from the tank/separator to the restricted rad support hardline to the canister. The problem is I do not have a quadrajet any longer. Instead I have an AVS. So the question is, what should I connect the carb port on the canister too? This is the two port canister, tank and carb,.
I have thought about plumbing it into the PCV line with a tee, but it seems like it is not metered and would just be a giant vacuum leak. Any ideas? Thanks,

A ported vacuum port is all that is needed for your canister.

If things are not factory correct, forget about it.

Ported vacuum will work for this as 77 has stated.
Some ran it through a temp switch on intake, but just hooked to ported vacuum is fine. Restricted pipe will keep car from having a vaccum "leak" |

Been running the canister connected to the ported vacuum port and it has been working great. No odor of fuel at all around the canister and I did not notice any change to the engine's response. Thanks for the responses!
