Charcoal canister line routing.

Didn't the 71's get plumbed to the PCV valve or something? Maybe it was the vent line that got plumbed to the PCV. The important thing is the tank vent. Maybe cap the other two?
The PVC was always to the carb up front. The vent line wasn’t plumbed to the PVC unless the carb was changed out where the suggestion of using a “T” to be used to connect them was in the carbs instructions. I agree with capping the others IF there is a gas smell issue.
If I can’t figure it out I’ll just leave it as is unless it smells like gas too much. Then I’ll have to figure out where one line goes.
Cap the canisters open tubes. This way the other line(s) have vacuum on them and operate as normal. This should prevent a heavy gas smell.
