My 1995 4.9 efi has all of the original vacuum lines and they are cracking and collapsing on themselves. What sizes of line do I need and how much should I get? Hoping to do this because i'm already removing the transmission to change the clutch.
Thank you for your help if you reply!

Do you have any recommended brands, and is 3/32 the inner diameter?

 

Good Info.........

Just what the caption says. It's the nominal diameter, which is inside for tubing.
