A bad pump handle that won't shut off, or an obstructed shutoff valve,
will cause a situation where more gas is being pumped in than the
bladder tank can handle. The bladder expands with the excess fuel, just
like a balloon. Pull the handle out and release the pressure, and the
bladder vomits the excess out all over you as it contracts back to the
size and shape it wants to be at the time.
And very seriously, you risk getting gas in the space between the
bladder and the outer (steel) tank walls. The Prius has sensors for
this. Should this happen, guess what the price is to fix the problem.
Are you really ready?
Really, really ready?
$000. A thousand dollars.
Yes. One Thousand Dollars.
People, use some common sense and don't top it off or otherwise try to
force more gas in than a well-running pump handle wants to put in it.

How can a bladder that is supposed to collapse as the fuel is used, and
meant to keep gasoline vapors from escaping, have a way for gasoline to make
it's way between the outside of the bladder and the inside of the metal
tank?? Doesn't make sense.

If I remember correctly, you don't directly fill the bladder. It goes
through the first tank, then into the bladder. I just don't see how this
can happen as you explained it.

A thread which discusses exactly such an incident, diagnosed by a Prius
A detailed description of the Prius fuel assembly in all its expensive
and horrifying glory:
(Nota bene: I'm a very happy Prius owner. Insert the fuel pump nozzle
fully into the fill pipe, keep your hand on the nozzle ready to shut it
off if needed, and don't even think about topping off.)

How would this be indicated? Will a diagnostic trouble code show up or
Check Engine light go on?
