My favorite from 260Z FSM regards the gas tank filler cap:
"Remove fuel filler cap and see it functions properly.
1. Wipe clean valve housing and have it in your mouth.
2. Inhale air. A slight resistance accompanied by valve indicates that valve is in good mechanical condition. Note also that, by further inhaling air, the resistance should be disappeared with valve clicks.
3. If valve is clogged, or if no resistance is felt, replace cap as an assembled unit."
LOL
