I know this is in the wrong section, but I am hoping for a quick awsner.. Our vacum hoses are 4mm? Is that right. I had one bust on me, and I need new ones that are non stock. Let me know if that is right..
 
We have several sizes.....it depends on what vacuum hose you broke.
 
All the vacum lines that are boost related are all the same size. I tried 4mm before, but they were loose. I think they might be like 3.6 or something..
 
AN-04 (.25" I.D.) works on the waste gate and BOV. You'll need to reduce down to 3/16" for the barb on the manifold.
 
I just use 7/32", it's a little loose, but it holds fine. If in doubt, get a twistie tie.
 
I kinda figued they wouldnt be nice enough to put all one size in. I ordered the 4mm as well as the 3.5 mm from hose techniques. It is way better to buy the per ft then a kit...
