    When shifting (manual) clicking sound come from under the car. When
    knock to gas tank sound come as fuel pump hitting the bottom, or foreign
    object is inside. Does anybody have this weird sound when knock to gas tank?

    Possibly a baffle came loose inside the tank. I saw this on an '01
    elantra, I think.

    What does it take to fix it? Can it be done without dropping a gas tank?

    To repair properly, you'd need to replace the gas tank if a baffle has
    broken loose.

    It's possible, however, if the piece is small enough, to pull it out the
    fuel pump opening in the top of the tank. There's an access cover for the
    fuel pump under the rear seat.

    What is the danger to leave as is? Can spark start and blow up the car?
    It appear from the sound that one site is loose and other is still
    intack creating resonanting/vibrating sound when bang to it.

    I'd not even thought about the sparking issue. I suppose it's possible but
    very unlikely. Probably the largest issue would be getting caught on your
    float and causing an incorrect fuel reading.

    Right. Sparking would not be an issue. The vapor in the
    tank is way, way below the explosive limit. That's why electric
    fuel senders (and pumps) can be put in the tank with no worries.

    Thank you all for your reply; it is very comforting to have such a
    quality support on line.
    As I mentioned from sound of it, it is more like musical instrument
    resonating - as you suggested one site from baffle is loose, making
    metal-to-metal vibrating sound when rapid vehicle change. I will
    therefore wait for next wormer day and try to fish it out through fuel
    pump opening. (or break of mentioned baffle) If unsuccessful, I will
    leave situations to observe further. Gas tank replacement seems
    premature at this point.
    Thanks again all.

    noise from fule tank elantra 2002

    pulled the pump and found the baffel was loose on one side but on a 2002 elantra it is one piece and about 1.5 feet long so i decided not to remove it,
    also very sharp so if you do decide to break it off with out removing the tank use leather gloves,
    i will check on aftermarket fule tank and before pulling the fule tank buy a new fule filer i here it is attached to the fule pump would be a good time to replace it if replacing tank
