If any vehicle will benifit from this , I think the vanagon will. The fuel
is injected almost directly into the cylinder and gets almost no time to
vaporizeor mix with air before it is burned. An engine on the opposite end
of this spectrumn is the old chrysler slant six. The intake manifold had a
couple of runners that were almost 2 feet long.The fuel had more time to
vaporize and mix with air. It still got lousy gas mileage.
