[s-cars] What does a failing fuel pump sound like?

So, if I go somewhere, park for a while, and come out and start the (warm) car, the fuel pump makes a bit of a groaning sound.
I haven't noticed this on cold starts.  Is this an indication of a failing pump, or perhaps just cavitation from fuel evaporation or something?
 
Or, perhaps the sign of an overly anal S car owner?
 
Thanks,
Erik
