I never said it was an unvented tank/cap!!

I said "I want to take a little closer look at why a bad vent could cause vaporlock. ... If you have a bad vent in the cap (missing or clogged) and if the gasket is old and not sealing properly".

The only place the tank gets vented is in the cap. I still stand by my post that a bad vent no matter where it is won't cause vaporlock. 2 different things vaporlock and a bad vent.

OK lets remove the word Vapor Lock.., dont you agree that with a bad or NON vented cap you can have the car shut down because the gas wont flow in gravity system?

Exactly the point I was trying to make. I do believe, your problem is because of dirty fuel system.
