I have only the 3.5mm line for replacing the vac lines in the engine bay. I'll be replacing the breather though - IIRC, someone on here said it was roughly 5/8" ID that you need for that hose.

 

I bought some 3.5 silicone vacuum and 5/8" breather hose and I am going to replace it all. I will let everyone know how the silicone works for a breather replacement. I do have one question on a vacuum line. When I bought my car it was partially apart and I can't find where the vacuum line from the blue vacuum reservoir goes? If someone has a picture that would be great.

 

Not sure if this will help but someone colored my ripped up vacuum lines

 

Do you know which one it connects to. It comes from the reservoir under the headlight and routes somewhere towards the firewall. I just don't see any that are missing a connection.

 

Wish I could be of more help.. out of town for another week before I get back home and do the exact same thing you're doing. If you don't figure it out by then I'll post a video of my process.

 

I did this about a year ago. I'm pretty sure it's 5/8 for the breather hose as well and used red silicone hose. I re-used the stock connectors and also put in a catch can in-line as I found more oil than I wanted to in the throttle body.

 

An oil catch can is a pretty good idea. Do you have any pictures showing how you mounted it?

 

I can take a picture of that tomorrow if you remind me, pm me or something. I just replaced the vacuum line cause It was all cracked.

 

Thanks! I'll bug you tomorrow about it!
