Vacuum hose sources & sizes

[racefourfun]

Since my 98 Mitsubishi is now 28 years old I want to change all of the original vacuum hoses with OEM grade or better. I have heard that silicon hoses collapse and many hoses don’t last long. Two questions , does anyone know the actual sizes of the hoses and secondly, where can I buy high quality ones?
Thanks

Most auto parts retailers will have large spools of it. Standard rubber hose won't collapse like silicone. Buy a few feet and start replacing.

Will do! I appreciate the advice.
