Vacuum lines are breaking, these are the colored rigid plastic tube type. I am looking for a source to replace or suitable replacement material. The rubber tubing seems to collapse; perhaps the walls are not thick enough. Thanks!
You can either switch them out for the traditional thick walled tubing or with the thinner hard lines like you have. Most of your big chains carry the hard line that you'll have to cut t length as well as the rubber couplings that go between the barb on the end device and the tubing.
Thanks for info! I inquired at our local Autozone and they didn't have any hard tubing or aware of it. I am traveling this week to the city and will check various places there; I live in west Texas, 240 miles form major cities!
