I've noticed my Carter buzzing along with the signals and dropping in tone slightly with the headlights, but considering my stereo is usually blasting at max volume I doubt the fuel pump is going to see a worse drop in power than that. I'm willing to bet the stock pump did the same straight from the factory, but it's so small and quiet and sandwiched between the body and underplate that it would be hard to notice. The Carter is just loud so we can easily hear when it changes in pitch.
