Unfortunately I have not found any vacuum lines that will do to replace this Cub Cadet hard line. The line is about an eighth inch OD, so I've been looking for a soft vacuum line that would fit over it tightly.

I cannot just replace the line with soft line because the CC fitting is designed for the hard line to insert into it, and you can't do that with a soft line. I could mess with the basis of the fitting to see if I could jury-rig a standard fitting, but am taking a real risk because some of those parts are no longer available.

I have found some gas line that fits over the existing hard line and will try that once the engine is running, hopefully in a few days. However, if there is any substantial vacuum involved, I'm afraid it will collapse. This is the vacuum that moves the idler pulley to engage the PTO and mower.

I have run into online complaints by many about hard plastic vacuum lines from moderately old cars - Ford products frequently - because they can't find the lines either today.
