Yes it seems that way. I had an old mechanic tell me the same thing and made new lines himself for another truck similar to mine. It seems like I am changing certain lines out every 3 or 4 months. 

I have a 1994 Mack CH 613 Model Truck that I recently put to work in my fleet. I seem to be having the same problem more frequent than I should. My injector lines keep breaking especially the ones that run directly behind the turbo. I already placed spacers to help with the vibration but that doesn't seem to work like they are supposed too. Any ideas or tips. I know the lines that run behind the turbo seem to be a bad place to run those injector lines especially since it gets really hot. Any ideas or suggestions?
