This may very well be the case for this set up of tanks but many have reported, including myself for the last two planes that fuel tank rivets show paint blisters which was not as a result of vent being blocked.

I am waiting to see if my new plane will show the same thing.

I didn't say anything about paint blisters being caused by a blocked tank vent.
The comment was related to an earlier post showing crushed nose ribs in a tank. They were caused by a blocked vent.

Hi Scott and others - my apologies for not reporting back. I have personally checked the vent lines - no blockages there. The owner has finally shared what has really happened. He had a puncture in a remote place and his son shoulder lifted the RV form underneath the tank and not on the spar. Expensive mistake

Years ago I have experienced it while test flying a new RV10. I looked at the left wing and saw how the panels were sucked in between the tank ribs. The FP was still good and I switched tanked immediately. No damage and the source of the problem was a piece of tank sealant blocking the opening of the vent line. It was a QB tank.
