    I became aware of a clonking noise from the rear of the E430.
    It sounded like something was clonking against the petrol tank.
    I found a very-corroded piece of steel small-bore capillary tube.
    It was not secured and was knocking about.
    It traced one end of it to a rubber tube connected to a small connector in the centre of the back of the fuel filter.
    This is on the rear left side of the car
    From there it trailed across the rear sub-frame to the right side and did not appear to be connected to anything.
    Looking a bit further, I found a loose red rubber tube connected into the fuel piping to the tank.
    In the end of the rubber tube was a corroded stub - Which I guess is where the steel tube used to go.

    It has obviously not done anything useful in a long time.
    The steel tube is so-corroded that it no longer has hole thru the middle of it.
    What did it do ?
    Does it matter ?
    Is there any point in replacing it ?
    Thanks for your replies.
