Requirement for fuel tank label - source?

Mel, I respectfully disagree. Is the point to obey an arbitrary rule, or is it to try to prevent a re-fueling disaster from some lineboy who has no idea what octane means? I say, the more explicit information, the better. New gas caps are cheap compared to a trashed engine.

I NEVER let a lineman fuel my plane without me standing next to him.

I'm much more concerned about him turning loose of the nozzle and damaging the cap flange (and top of the tank) than having Jet-A put in a little piston plane.

Me neither -so far. But some day I might forget to tell them to wait for me. I'm also afraid they don't know the 'push down to release' operation of the gas caps.

How easy it is to be misunderstood. The red was also part of the quote.

No. My point was that when 100LL goes away, you will have to get new fuel caps because you can no longer fuel your aircraft with 100LL.

There is no problem with having "100LL" on them now, but later it can become a problem.
