Cruise Control Vacuum Line Size

In working on my car I noticed that the two vacuum lines need to be different size at each end.

The hoses I took off were 1/4" and fit one end properly. At the check valve and at the brake switch.

The other ends attach to the servo, one should be 3/8 and the other 5/16, the hoses that were on the car were stretched to fit. I find this odd.

Looking at both the parts book and the service book make no reference to this.

Does anyone have information on this, preferably and original system...
