Would your Van happen to be a turbo diesel? Yeah, vapor injection isnt anything new. it is used to cool the intake charge temp. Although very useful, propane is MUCH more effective. These things are ONLY used in boosted or juiced applications though. They DO work, but as I said, only really for boosted applications, where you have a turbine creating heat. Otherwise, it is mostly useless unless you are cooling the vapor (propane is cold because of pressure). Honestly, I wouldnt bother on a stock vehicle and DEFINATELY not on an N/A engine.
