Everyone had good answers. I was researching this recently
and read an interesting discussion on condensation. The author
felt that condensation was extremely unlikely to occur, and
that this was a myth. I tend to agree with him.

I'd say pumped on, faulty filler cap, ingress via fill hose cap and
the vent hose. That assumes you have no hose leaks--which
would be pretty obvious.
