I have not been following your adventure from the get-go so I'm not sure what you are up to. I suspect this has something to do with gas mileage.
I tried something similar once in 1979, actually twice, but the second time does not count because I knew what to expect.
I won't go into the boring details, but I had a new 1979 srw 1 ton chevy pickup I converted to LP. Actually it was dual fuel it could run on LP or Propane. I only tried LP. I also installed a US Gear under drive over drive unit. Gas mileage was as big an issue back then as it it was recently. At the time there was also a BIG push to migrate cars in the US to LP much the way it was and is used in Canada today. In the little town I lived in southwestern Ohio one of these stations was put in.
The 454/400 in that truck with a 4.10 rear got 10 mpg before I "converted" it. After I converted it I got 21 mpg on the freeway in overdrive...I was not impressed I was epxecting closer to 30 mpg...never happened.
What I got out of this was a nice tax write off on the purchase due to the tax laws at the time thanks to the oil embargo in 73, a little bump in mpg on a big truck and no towing power. The LP conversion worked from the get go without any problems and was easy to switch back and forth. I can't say the same for the other "parts". The one big benefit I got and will never forget was how easy that truck started in 22 below weather on LP.
I got all of my money back when I sold everything plus I made money when I installed on their motorhome. They loved it, even though they blew up the other "parts" two times. The manufacturer finally replaced the gear box with an upgraded overdrive only which fixed the problem.
Good luck with whatever it you are trying to accomplish.

Doc,
No Vapor System as such. What I was refering to is some of the old material we went over very quickly when you were here. I will look through that material and see if there is any referances to some type of Vapor System and let you know if there is.
I have mostly abandoned my messing with the Hydrogen stuff I was playing with till I find a lot more concrete info.

Doc,
Over on "Ford Six Performance Index" forum , there is a very long discussion about getting the most out of the fuel being burned. Some of the same as what you are trying and there is a lot of info there. Go to the site, then under the heading "hardcore Inline Tech" find the thread titled "100 MPG". I don't think you have to join to read it, but even if you do, it is well worth the trouble to register for all the information over there. I am over there too, mostly just read things, but do contribute to the "vintage" area now and then.
