If you suspect the fuel pump might be making the sound, do a rail pressure leak test and see if it starts sounding bad is pressure reaches maximum.

If you suspect it is the air compressor, disconnect the intake and output air lines from it and see if the sound is much less. As well, I would think that the sound would likely mostly go away when the air compressor was not active.
