If you wanted to construct a new line with rubber vacuum hose you need to save the end fittings and nuts. Check valves can be had as in the attached picture or they have plastic ones. EBay and Amazon sell them.

You will have to find something that works for the little nipples to T into the main line. It could be done with Brass fittings.

I replaced the plastic tubing on my Power Brake Booster Vacuum Line with rubber vacuum hose. I increased the length so I could run the line over the top of the fender well were it was less likely to be damaged.
