60mpg? i'd believe it, assuming fuel, not figured into the mileage, is flowing from the tank in the trunk twice as fast as it comes from the blazers regular tank

assuming the gas tank in the trunk is gasoline, gas vehicles already draw vapors from the tank via the purge valve

You can get 90 MPG in a lot of vehicles, it you only average 20 MPH and engine off P&G.

They did 124 in a 1970 Opel Station Wagon around 1970. Limited throttle travel, 15-45 P&G in 3rd gear, engine off coasting.

The real challenge is doing it so it can not be detected in normal traffic. We have KNOWN HOW to do it for at least 70 years.

People come here to share ideas Gaud, What you're sharing is? Unsupported claims without real unbiased testing. We're supposed to believe everything you say. I remain skeptical, in much the same way you would if I told you something your experience just would not let you follow.

Without real proof?

If his "gadgets" are an electric motor, controller and a pile of batteries, 100 mpg might be doable.

I love how most Unicorn discussions eventually end up with this suggestion.

Actually if you think about it, all modern gasoline fuel systems are vacuum driven gas vapor systems.
The gasoline is exposed to vacuum anywhere between the throttle and the top of the piston, until the valve closes and the air fuel goes into compression. When driving down the road you can expect to run between 15 and 22 inchs of Hg. That's a vacuum of -7 to -10 psi.
Heat in the fuel that gets picked up on its way to the gasoline induction system combined with exposure to the vacuum should flash all the gasoline to vapor in the warm to hot vacuum environment.

If that was true, then newer injectors wouldn't be going towards the trend of smaller and higher number of holes (example ev1 vs ev12 injectors). This is true of port and direct injectors for diesel and gas engines. This increases the power per given fuel injected.

The OP's statement for the operation is faulty though, in that the closed loop operation is not responsible, since he implies that the total quantity remains constant. If constant, there is now savings. The explanation I gave would, but I have yet to see it documented correctly. Adding a system like this would also throw the fuel rich/low zones (important for high swirl chambers) off kelter, since the pulsewidth and air mix would be changed.

In short, no proof, and gets too complicated for sweeping generalizations. But, I would be open to hearing a constructive discussion on the matter.
