well, the fuel pump primes itself and sounds like that, but you can distinctly hear it comes from the rear of the car underneath.

Also, it could be the sound of the air pump, which is located behind and below the drivers side headlight, in the bumber. Mine made noise fpor a little while once, then I never heard it again.
