Electric fuel pumps can be expected to make a humming noise because they have an electric motor inside them. Excessively loud humming can predict impending failure. You should compare the sound to other cars of the same make and model. If the noise is significantly louder, it is time to be saving up for a repair. A trusted technician would really be a good resource for you...a good tech can tell a lot from the sound.
