Agreed. I do stand corrected. Bogus, in the sense that it didn't require
anything to be actually repaired and/or replaced!!

I think it is illegal to top off in many locations, and many pumps have
warnings not to top off...

Listen to Ray and you can avoid all sorts of problems ;-)

BTW, most check engine light items will not noticeably affect drivability or
MPG. If the light is flashing, turn off the engine and call for a tow.

Bladders are generally used in race cars so that the fuel does not spill if
the tank is ruptured in a crash. In the case of the Prius, it is used to
reduce the air space in the fuel to reduce evaporative emissions. Here is a
good explanation and picture of the bladder:
