Vacuum Lines
Hey I just replaced all my vacuum lines yesterday, and pcv anyhow, I used 1/4" fuel line, it's thicker and should withstand all that heat from the turbo better than a stnadard thin walled vacuum line. Get 3' of it, to replace it all, you will also need 2' of 5/32 and 2' of 7/32 regular vacuum line. Just be sure to do one section at a time so that the chances of getting something routed wrong are reduced. Also replace all of the clamps while you are at it.
