Has anyone ever noticed a vacuum line with two white stripes?
I am trying to identify a vacuum line for the k30 option.
I can post a pic but it looks similar to the Vacuum Advance line. It is a bit larger than the Advance line with a white stripe on one side (same as the Vacuum Advance line) and another thinner white stripe on the other side. There are also ridges on the exterior that run the length on the tube, parallel to the stripes. There are three on one side and one on the other side.
Does anyone know if Corvettes used anything like this?
How about on any other GM vehicle?
Any help is appreciated.
