Vacum line diameter/size for diverter valves

[Frizo]

I'm going to be replacing the DV's and wanted to replace the vacum lines associated with it and in that surounding area. The ones on there look original with the cloth like material wrapped around them. I know I could measure the inner diameter of the original ones but figured I'd pick some of your brains. TIA

BTW im installing Forge DV if that makes any difference.

I just went to autozone and got 3mm vacuum hose. Seems to work fine.
