Hey how's it going.

Looking to replace all the vacuum lines in my '88 Turbo Coupe. I've searched up and down on the forum and couldn't find an answer. 

Anybody know the Vacuum line sizes needed? I know there are a few different sizes. I'm trying to order hose without having to run back and forth to the parts store.

Thanks in advance.

Measure the ID of all the lines you want to replace and buy them from the parts store or Ebay. The OD doesnt matter. The OD of the lines doesnt matter. The thin Nylon lines can be replaced with regular 1/8" ID rubber lines.
