    I assume that's what it is since it's an electrical motor noise. Happens when I'm stopped at a light. It comes and usually shuts off about about 10 seconds. If I just barely touch the throttle, that will stop it too. Do you think I'm correct in my assumption?

    Fuel pump is usually a loud hum coming from the trunk area. When the FP gets loud it does not change tone in my experience.

    Loud hum would describe it. Does that mean it's getting ready to go out?

    You know most will say yes, including myself. I did have a buddy with a loud one that lasted over a year, he eventually replaced it anyway.

    I have a very loud fuel pump as well. Replaced it with a new one, still makes noise. Very annoying... But it's been like this for over 2 yrs now.

    The new pump still gets loud sitting at intersections sometimes. Any thoughts?

    Louder than when it primes, yes. It's pretty audible over the exhaust.

    It's got Flowmasters on it so it's not exactly quiet.

    I can't really remember ever hearing my fuel pump even when it was stock other then when I primed but I am not a motor expert by any means.

    It should be running the entire time the engine is, right? No cycling? 97 Cobra since I don't think I mentioned.

    Is your AC working? The A/C cycles on and off if it is low on r134a and the compressor clutch can make some noise if burned out!

    Good thought but the a/c wasn't on during any of these instances.

    Mine was super loud because i didnt have a back seat or anything back there. Soon as i put a back seat in.. its pretty quiet now.

    I replaced my pump with a walbro 255lph i think and it was loud as the bad one right after the install. That all changed when the seat cushion was installed.
