Hello, was yesterday with the TÜV and unfortunately not passed, because the 3 pipes are corroded from the tank (see pictures). The question is now whether it is enough if one separates the corroded pieces out and replaces the gas hoses and hose clamps so that the examiner is satisfied? Since the pipes are difficult to access (runs above the petrol filter), I could only separate the line to the places marked on the picture.The length to be replaced would be by the many bends and curves, about 70 – 100 cm.
