I have a 73 bronco with no emissions on it and I am looking for a gas cap that is vented like the old broncos but fits the 73 neck. Is this vented like the old ones or is it for a stock system with a cannister?

This is a vented cap, like normal. It allows air in, but no fumes out. We use the same cap with or without the canister.
