The air system in my truck developed a leak. The tube corroded under the clamps that held it on. A new tube was not available and would have to be ordered from the factory. Luckily I was in Mn. anyway so I just went home and welded it up. The tube runs from the engine compartment to the sleeper, over the step and muffler. Was a real bear to get out because there was no room to work.

The line is about 8' long and was corroded in 4 places.

Welding corroded aluminum is alway hard, but this thin tube really tested my skills. I had to start at the edges and lay new aluminum over the top, the heat it to cook the corrosion out which floats to the top but leaves pin holes behind. Then I brush off the junk and do it again. You just keep doing that til stuff quits coming out, or you get the pipe sealed up. Here is what they looked like done.
