What type of tubing for vacuum gyros

[Rick G]

Can anyone tell me what type of tubing I should use to redo the hoses on my vacuum gyros? I need to know what type of hose and what sizes are common. There is an input and output and also one smaller line that seems to go to the vacuum gauge on the right side of the panel.

In my previous thread I installed an AV-30c. The next step is to swap positions with the vacuum attitude indicator. To do this I need to extend the hose lengths.

Thanks
