Fuel tank vent?

I just got done removing, cleaning, and reinstalling the fuel tank on my '69 C-10. I also replaced the fuel pick-up/sender assembly. I got to thinking, where is the fuel tank vent? The cap has a rubber O ring so I assume it seals tight. As you draw fuel out of the tank it looks like it would create a vacuum. How does air enter the fuel tank?

Re: Fuel tank vent?

I believe 67-71 fuel caps (on the filler necks) are vented. I'm sure someone will correct me if I am wrong.
