<VV> anyone have a diagram for homemade vapor injection?

[David Fasgold]

LOL...
I found the diagrams in my tech guide...but judging from the responses I've got, the vapor injection sounds like a waste of time. I'm not really interested in the water injection, since I'm only running a 95hp anyway. Maybe if I was running a turbo... Anyway, thanks to everyone who responded. 
Later,
David

Others have pointed where there are instructions to make these. The 
bigger question is WHY?  Water vapor gizmos don't do anything!  The 
NORMAL combustion of gasoline in the combustion chamber makes WAY WAY 
WAY more water vapor than these vapor gizmo things put out!  Roughly, 
a gallon of water (if you condensed it to liquid) is produced for 
EVERY GALLON of gasoline burned!  How long does it take the mayonnaise 
jar + fish tank contraption to go through a gallon of water?

So does it hurt anything?  Well probably not, but it makes you look 
like a kook (if you built your own) or a sucker (if you bought one).

N.B. -- Liquid water injection is a WHOLELY DIFFERENT story. The 
liquid systems inject under load (the water vapor things do it under 
vacuum, the worst time). Also, the liquid systems cool the charge 
(enabling higher volumtric effiency & knock limits, especially on a 
boosted engine) because you are making use of the heat of vaporization 
of the liquid water (it sucks up heat to vaporize the water 
in-engine).  So liquid systems can be useful, but vapor systems are in 
the realm of fuel line magnets and scattering chicken bones on the 
hood of the car.
