What size vacuum hose?
If I wanted to redo all my vac hoses with silicone ones, what sizes and how much of each would I need? That is if anyone would know. Thanks for any help.

3.5mm Is just right. Going 4.0mm, for example, Is not neccessary. It's more likely to lead to popped off hose ends as opposed to 3.5mm's. Providing you don't zip tie them. I used 3.5mm's In both my NA and TII.
