    Default Very good Cessna fuel tank leak article

    This is a good explanation of why so many C-172s have fuel stains behind their fuel caps.

    He did not really cover the part about how the little rubber flapper valves in the cap's vent system can leak. Particularly on the ground with full tanks if you hit the brakes or go over bumps so the gas is sloshing around. The little flappers just let the gas go right out the two vent holes...
