Hello, for some time now I have also been affected by the water pipe problem. My carriage has now more than 300K on the hump. There is the possibility, i.e. the danger, that the previous owner has already installed a telescope pipe. Now, since I do not see it, for a pipe, which disappears under the suction bridge, and only because it shines and co. 100 Euro to pay the Americans, and 300 Euro for a pipe from the east, I created the pipe myself. I am also I am sure that my creation is safer than a pipe, which is fitted with thread on both sides. In addition, in contrast to the addressed pipes, I have not rejuvenated / reduced the inner diameter, but extended it in the middle range. (Alu socket approx. 240 mm) Ø 40mm inner diameter and 36 mm, wall thickness 2 mm. Since the original tube has a Ø 35 mm, and the socket has an inner diameter of 36 mm, and 1 mm unfortunately are not little in this case, I have on my tube, a So the tube sits in the sleeve with very little play, and on the one hand there will also be better hold for the 2k glue. Finally, I will cover the one side, the old cooling hose for safety. With the hose it will become really tight under the cover, but will go. On the front side, where the origin of the evil lies, I will be able to put the seal, also liquid-proof. I will start the operation next week. I intend to do the procedure without expanding the water pump. Until then, I am very grateful for any tips and co. Perhaps one or the other has a better idea or maybe “criticism” regarding my approach. I am also grateful for all the instructions that have been published in the Net so far. Greeting John
