On the air vac vacuum pump I took an old hose from one of those screw-onto-the-can recharge things and cut off the end that attaches to the can. then I replaced the fitting on the vacuum pump with an 1/8" NPT fitting with standard hose barb on hte other. One hose clamp and it was ready to go.

the biggest PITA was the fact that my compressor was too close to the sheet metal to get the lower hose on the fitting. I had to loosen up the compressor and slide it towards the fan in order to install the hose, then re-adjust it before starting the engine. Repeat every time and for when I had to remove the hose. But I got real good at it.
