That's a good question that I've often wondered about too. Maybe Ross or someone else has the answer? I know my 1965 Cadillac is non-vented as it has a separate vent line from the tank to the fuel filter but that was only on cars with A/C. I'm not sure how the non-A/C models were even though I used to have one but I know they didn't have the extra line.

Ross, on the cap's ridges, I went back out to the shop briefly this morning to take inside an early delivery of lumber before the rain starts again and had a look at the cap. The inside appears to have a second piece of steel where the gasket seats and if that's the case, then the ridges likely vent through the notches that are on the inner piece between the inner and outer pieces. I can't actually see the ridges at all on the inside but that's the only thing that would make sense.
