I was wondering if anyone knew the diameter(s) to the vacuum lines on my 1993 Legacy Turbo. It looks like it's about time to replace them, and just need to know the size(s) before I go and buy somemore...

I should probally install a boost gauge while I am at it (I have read all the threads about installing them, so I know how to do it now )

Well, I now found out that one of them is 4mm, so those will be the first ones I replace. I think I will do one size line at a time and find the sizes as I go...
