When my foot is on the gas I can hear a howling/moaning sound which sometimes its low and sometimes the howling is real loud, speed doesnt matter really. It's coming from the back, I assume it might be the fuel pump b/c it only makes the sound when my foo tis on the gas. Are stock fuel pumps suppose to be loud or low or inaudible? Is it dying? How expensive are they?

Mine whines, but I can only hear it if I'm standing by my rear-end.
