Change it!
Humming noise=on the way out. Change it now. Do a search, you will find more info on this topic. Most places won't take back electrical parts...
Good luck!

Every Bosch fuel pump I ever owned made an audible humming noise. Its only when it becomes abnormally loud that I began to worry.
They are not silent my any strech of the imagination.
