Ever seen one?

Nope! Interesting!

That is neat. Also likely one of those things that after a few times at the pump ends up rolling around the floor board

Scott, it might go well with an aftermarket period correct grill?

Haha that it would. I was actually really tempted at the novelty of it but in practice I know it would get thrown in the door pocket pretty quickly.
Hopefully someone here gets it and reports back on it.
Wonder if it only works pre-flapper?

Me either!, but it wouldn't last long with me either...lol.

These are incredibly annoying lol! My truck came with two locking gas caps and in a state where you don’t even have to get out of your car, having to get out just to unlock a cap or give the keys to the attendant just ruins that quiet little moment of contemplation.

They were listed in some of the accessories catalogs, if I recall correctly.

I had one of the traditional style locking gas caps on one of the dual tanks in my F150. I was never given keys for it, but that didn't happen to matter because it popped right off with a small pry-bar. It was more of a deterrent than a lock.

I wonder if anyone has attempted to put a anti syphon screen in the tube... this eliminates any need for a locking cap
