Sorry I wasn't more clear. The lines that I was referring to are the clear ones that go into the vacuum module. The info that I was looking for was what others have used to replace the very thin lines or to repair them. They are brittle like glass; tried to use fuel injector return line to bridge the gap but wound up breaking them again in another place.

Thanks for the speedy reply and for posting the picture.
