Humming noise from the rear/gas tank?

Occasionally I get a loud humming noise from the back. The best way to describe it is the loud sound an external aftermarket fuel pump makes, but it's definitely a "hum". Most of the time it happens when I'm in reverse backing out of my driveway, and a few times it happens in 1st. Lasts about 3-5 seconds. I would say most of the time it happens after startup. I don't think it's the drivetrain, and I know if I take it to the dealer I will not be able to replicate the noise on the spot. Any ideas?

Thanks in advance.
