What size vaccum lines do you use?

[guidoxpress]

just researching some stuff for my future turbo build, and i am not sure what size vaccum line everyone is using.

Does ALL componets in the turbo system use the SAME size line? If not, please post sizes for what componets if not.

Thanks!!

If you mean boost lines (i.e. boost controller, boost gage, fuel box) I've always used 1/4"

yes sir, just what i am looking for...

so same 1/4" hose for the wastegate and manual boost controller connections too i assume...

I used 1/8 in for boost signal lines to fuel reg,boost gauge,and controller.
1/4 in for the waste gate controller,and 3/8 in for the vacuum/boost line for the BOV.
Actually all are fuel lines . A little thicker and tougher.
