Hello you love, and indeed I have various problems that are probably related to false air therefore I wanted to replace all diesel lines as far as everything is exchanged only I wonder, where the line from the tank leads to the fuel filter or diesel preheater long? Do you see the line in the engine compartment, also ask me if I have to make the car on a lifting platform or if so? Would be great if someone could describe to me the way this Lei I have already looked for in the book “So wirds wirds” but there the chapter diesel pipelines is missing probably completely and completely greeting Tobi
