Ok well I wanna get rid of all the old plastic vacuum lines and convert them over to rubber ones to ensure I do not leake vacuum. My simple question to you guys is, what size rubber hoses will I need to redo every vacuum line? Thanks guys.

 

I fairly sure the measurement is 7/32". I used a universal hose that fit 1/8-1/4 and it worked fine. Replaced lines both plastic and rubber and havent had a problem.
