What are the three ways water can get into your fuel tank?

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.

Bart,
I'm not sure what would make an onboard tank less susceptible to
condensation than our 10,000 gallon surface diesel tanks, but they get
condensation all the time and we have to pump them out regularly.
