Had a friend of mine invest in a company called VGAS back in 1980-81. Bought 2 shares which got us 2 units and a seminar on how it worked and how to install it.
Came with an O2 sensor , a small processor, and the tubing and solenoids to divert the liquid fuel into a canister in the air intake to help vaporize the fuel before going into the intake.
Installed it on a 1978 chevy 1/2 ton truck, worked out the bugs, and he drove it back to the company to buy more units . He surprised them and they wanted to see what we did, to make it run.
Guess we were the only ones to get it to work, and not long after they were gone from the facility in Wooster, Ohio, where we saw the built.
They drove the truck for a couple of years--towing a boat to Canada and back a couple times. So the theory works.......
The unit was bulky and sure wouldn't fit in the engine bay of a Chevette. It got 1 to 3 MPG better than stock......By 1982 or 3 GM's computer controlled carburetor did that, and then FI surpassed that.
There used to be a HIGH MILEAGE CARBURETOR CLUB, and they had a book with lots of diff. patents and designs shown, and what company bought it, and the demise of the inventors. Many disappeared or had "accidents". But the weirdest thing that I experienced, was when I got back from the seminar, and was telling my wife and her mother about what I learned, my mother-in-law told me a story.
She was not technical, but during the war, worked at Federal Machine, near Warren, Ohio as a receptionist. Some British officers came with a box to install on one of the halftracks that were built there.
One of the old farts at the seminar told a story about when he was in London during the war that they used halftracks to get to town sometimes and one would get twice the mileage and accelerate like gangbusters.
Two people, different places, kinda the same story, different parts.
