Is your tank empty? Mine gets reallllly loud when I let it get real low. Other than that, I guess it could be the filter on the fuel pump itself. Change that every few months, and it won't make noise.

Either that or it's going out. They tend to make a bit more noise when they're about to die.

Yea most likely when u tend to run ur car on a low tank most of the time, you will hear that SOB scream! Give Me Gas! If you run it low all the time, ur pump will go out sooner.
