smokey yunick took an 80's chevy to a hundred MPG by preheating fuel.

think this is the link: Henry "Smokey" Yunick -- Fuel vaporizing carburetor system

personally i felt carburetors were never fully explored.
i once heard of a 70MPG carb having been left on a 70's dodge pickup and accidentally slipping off the assembly line...
chryser got wise to its mistake and offered a brand new top of line truck in exchange for carb alone - to no avail!
I am surprised the big 3 didn't pressure him to stop work on this. However, we haven't seen this engine in production...naturally.

I have seen a couple examples of people heating fuel for FI engines. I was told that part of the work in the combustion chamber goes to heating everything up. If the fuel is already heated, we are that much closer, and should (the operative word) require less fuel for operation.
Here are a couple to choose from: maesco.com :: RACOR :: Diesel Fuel Heaters I prefer the coolant ones.

stovie ,,

Very Interesting
you said "quart jar of gas to the vacuum lines "

ummmm , not gasoline , its too explosive when it vaporize and the vapor pressure is very lowwww on it but ......i am dabbling with other mixes ,, Soup i call it

RE: water injection Snow performance makes some very big claims about it , even in NA[naturally aspirated] machines using Methanol/Water mixes

but here is a grass roots system i like the looks of
Kiwi Style
MW50 to the Vacuum System

Water Injection By Robert Mann
consultant ecologist

search 'water Injection+New Zealand'
you might hit it
claims some significant FE increase ,, 15-20% ,some one should test it and see if it proves ..

seems like your manifold vacuum is not so good , i run about 15 INHG at cruise ,
i have a quart jar with a mix running to the intake manifold
don't mess with no stikin vacuum line, goes straight from the pickle jar to the intake manifold ,MW50 , Castor Oil and MMO[mystery Marvel Oil ] in it now .

soon i plan on running trials with Top Fuel in there.
see the thumbnail below

we shall see what we shall see...
