Vacuum Hose ID Dimensions - 1980 Trans Am 4.9L

[1980Transam_Red]

Hi

Just wondering what the Inside Diameter of the vacuum hoses for a 1980 Trans Am 4.9L engine is?

When I measure, and due to the hoses being old, I have a few different measurements.

If I wanted to order new hoses, is 4mm, 6mm, and 8mm ID enough?

And how long should I order? 10 feet, 15ft?

Any help is appreciated.

Thanks

Mike

Did you figure it out? I have the same issue.

Did you figure it out? I have the same issue.

Hi, I ordered all three sizes and 10 feet for each.

Since my car is red, I ordered all three in red.

Not finished, but a start.
