- Here's how I replaced the vapor canister in my C3.
"The heart of the EVAP system is a canister filled with activated carbon. The carbon absorbs gas fumes from the tank and stores them until being released and drawn into the intake to burn with the engine’s air-fuel mixture. "

Very helpful video, thanks. I was looking for such a video. Have the same old canister on my '74 Corvette. Will replace it with the newer one. Do you add a rubber line on the AIR- inlet or just let it stay open?
Glad I could help!
The aftermarket canister has a little plastic shroud covering that air vent, so it's not completely open. Is there a reason why it would need to be covered?
@@ingrownhare9211 Sincere thanks for your reply. That's the question. My thought was that the air vent at top of the new canister (big pipe with shroud at the left) was the same the old one has at the bottom. I don't know the sense of the shroud, because you can buy such canisters without the shroud too. Is the shroud completely closing the pipe? Or can air escape the canister with the shroud in position? It's even possible, it's just a protection against dirt or water entering the canister. Wasted a lot of time in the internet without finding an answer. They should make these things like the originals.
@@KAMR4 I think you are correct. Functionally, the air vent at the top of the new canister is likely the same as the air vent at the bottom of the original canister. And yep, the shroud does indeed appear to only be there to block contaminants from entering. I've put a few hundred miles on the car since I replaced the canister with no issues, and the gas smell coming from the car has lessened (although it is still there). Because of that, I am fairly confident that I replaced the canister correctly.
