ok...will do. I do keep good record of my mpg's so it will be accurate. Btw...the vaporizer I made in 1982 was the only change I did on the '62 plymouth fury and it went from 13 to 28 mpg's on the highway. I know you find it hard to believe but that's what Charles Pogue did but of course much more efficiently and he used hotter exhaust gases. I just duplicated a simple invention that I bought from the national car drivers association in Washington. I don't know if they still exist? But of course that won't work any longer as the gas has a higher vaporization temp nowadays, unfortunatley. I'm sure it will work using the exhaust manifold or gases though. It's just a bit much for me to do working long hours as it is and a limited income.
