If, you do Not restrict it, you'll basically have a vacuum leak.... at your gas tank..., albiet through some charcoal on the engine end of things.
This line fastens to to the bottom rear of the core support. One end comes up by the battery tray/washer tank, other is near the canister., Rubber over the DS inner wheel well to the pipe coming up with the rear brake line.
Thanks Bruce. I’m thinking a slightly oversized plug with a small hole in it inserted in the rubber hose just about anywhere between the tank and canister would work. Any idea what size hole that should be?
