Default Vacuum line sizes?

Hey guys,

Does anybody know the correct sizes on the engine vacuum lines on an '81? Im going to replace all of mine but they don't have any sizes printed on them. I am just wondering so I know what sizes to get at the parts store.

Thanks,

-Joe

Joe,
I’m glad you asked this Q, I have an 81 and I am about to do the same exact thing, including putting the charcoal canister back in that the PO took out. I have the AIM but it doesn’t specify the diameter and length for each vacuum hose

$12 bucks worth of hose from your favorite auto parts store. And I'm sure you won't have to wait.
