Fuel tank vapor line

[Howler73]

I just noticed that the "vapor line" coming from the fuel tank is just sitting open by the firewall on the passenger side. In my manual it shows it going to the vapor canister then to the carb base plate. I don't have a canister so can I just block it? Or is that also used as a fuel tank vent?

I believe that is the vent also. Im in the same boat also. Ive been looking at carbon canisters online but im not sure how to secure it. Dorman has some around 50 bucks

Thanks, a previous owner put a 350 crate motor in and just left the front vapor line, as it’s called in my overhaul manual, open. I think I’ll find some kind of vent cap instead of hooking up a canister.
