Me too.

Not sure if expansion tanks end up with fuel in them when at gas
station and filler pipe filled to top, but maybe later on if
conditions caused fuel to expand enough.  (hot day, altitude maybe
too?)

My understanding is that the expansion tanks are there (in part
maybe?) for that reason.

The top of the filler pipe is higher than the tank so I"m thinking
that at least the fuel expansion tank hoses would fill with fuel when
filler pipe filled to/near top.
