@proporsche,
The photo below shows where I have the vacuum check valve located (circled).
John certainly knows his stuff, but I will add that I've been driving the car with this setup for 37 years, and have have not had an issue with losing brake boost yet. Perhaps the long run of tubing from booster to engine provides functionality similar to a vacuum canister - as long as the check valves are doing their job. But a dedicated vacuum pump would seem to be an improvement since vacuum is being pulled from just one cylinder (what is the failure rate on these pumps?).
