Does anyone know where I can acquire the vacuum lines for my 1988 Audi 90E saloon,also, where can I find a diagram of where to to actually fit them once procured...according to a local garage, the vacuum system is in a real mess with some of the pipes missing, and others melted, I would like to keep the car, but this is a problem that I have never encountered, and I'm not sure that I can handle it.
