What is this part?

It was floating in my fuel tank which I was cleaning out because of stalling

Good grief that looks like the stopper that pops up to drain a bathroom sink.

It looks like part of a “gas can” nozzle of the newer safety nozzle type.

Yep, safety gas can spout valve.

It looks like part of a “gas can” nozzle of the newer safety nozzle type.

I'll add this to long list of reasons I don't buy those cans.

Makes sense.
Had to have been the dealer, as I bought it new, and only use VP racing 5.5 gallon fuel jugs (no valve).
Afraid it was part of the fuel sender or something.
