Running engine off gas vapor only

So the videos I posted must not be legit then? Must be a hiding gas tank and carb not shown someplace.

There's a lot of non-legit videos floating around on the interwebz.

I don't see why the video wouldn't be legit. It's perfectly reasonable for the engine to run on gas vapor like that. What isn't reasonable is the expectation that there would be any kind of fuel savings. Stoich is stoich - there is no getting around the math.

Hot vapor is another story. The theory is that a super heated and pressurized fuel vapor can run extremely lean afr's - resulting in less fuel being needed. In practice though, the heat generated by the process is more than a standard engine can handle as far as longevity goes. Would likely need ceramic engine components or something else as durable for it to be reliable
