Fuel Line Insulation?

What do you guys think about this?

I remember reading a discussion about a former MPG-record holding vehicle - one of the tricks they used (at least as far as I can remember) was to heat the fuel lines and turn it into fuel vapor, which was able to burn more efficiently.

What are your thoughts on heating/cooling/insulating the fuel lines and what possible effects it might have on fuel efficiency?

Can't see how it would help, modern engines already are very efficient burning 98%+ typically so even if hotter gas burned better you are only shooting for an improvement of 2% or less.

You link didn't work for me.

Try this one.

It's a question of getting the fuel to vaporize better. It might help in colder weather, not so much in hot weather.

Now that I can read the first site posted that site has nothing to do with fuel vaporization. That article seems to be trying to keep the fuel line cool so that it doesn't cause vapor lock with boiling fuel in a hot engine compartment, and doesn't talk about heating the fuel at all. Unless there is a vapor lock problem there is no benefit or improved vaporization.

Preheating the entire engine has some benefit but warm gas alone, not so much.

Even back in 1961 it did not seem to work.
