Of course, for all I know, it might not be a concern with such a small ratio or propane.

Less Crude than just dumping a hose into your air intake, but DIY installation, yes.
It meters out depending on the engine vacuum at the moment, and you can manually control the flow from inside the vehicle, from .5 cfm at idle to 1.5 cfm at full bore, or any variant thereof depending on how your car reacts to it.
