What is the ID" and OD" of the vacuum line used for the diverter valves?

My vacuum line to the diverter valves needs to be replaced. Local shops don't seem to have anything this small.

Does anyone know the ID and OD of this line? I want to order some of McMaster. Thanks

I have Forge DV and i am using vacum line with 3mm internal diameter.

Outer diameter is about 1/4" and inner seems to be pretty small. I bought some hard vacuum line from Autozone and it didn't work. Make sure the tubing you buy is flexible because it has to slip onto some pretty tight fittings

I'm a little disappointed that my AWE valves didnt come with extra tubing. I'm a little concerned with the heat buildup in the engine bay with any old over-the-counter tubing though.
