Well, I will tell you my results. I tried it on a 96 ford ranger and it didn't work out. First I built my hydrogen generator and made a torch, I was able to burn thru paper clips(don't laugh). After I made a better HG that produced a lot more gas I started having flash-backs and kept blowing up my bubblers, so I quit with the torch. After a lot of experimenting with amp draw and how much lye to put in a gallon of water I felt confident enough to install it in my truck. At first I installed the HG and bubbler and did no other mods, I lost 2mpg. After I leaned back the fuel by extending out my O2 sensors, milage went back to where it originally was. I ran it for about 5 weeks before I took it off. I've come to the conclusion that the new computers (obd2) in 96 a newer vehicles is hard to fool, I wish I had a older vehicle with the older computer, a carburated vehicle would be even better. If I had a carburated vehicle I'd definately try it again. Dave
