<VV> Fuel Tank Collapse

[FrankDuVal]

Um, I guess they did, since there are vented and unvented caps used 
throughout vehicle manufacturing.....

Depends on where the engineer decided the vent for the tank should be. 
Only time there is an issue is when people buy the wrong cap, not 
following the cap manufactures vehicle use chart....Or the cap 
manufacturer follows the new regulations that tanks can inhale but not 
exhale. Seen that one too many times on a hot day.
