Insulate Fuel Lines
Under-hood engine heat is a serious performance robber in almost
all cars. Not only does the under-hood heat cause performance
loss by heating up the intake air, but it also causes
performance loss by heating up the fuel lines. Cooler fuel will
help cool the intake charge, as well as provide for a better
overall mixture.
In order to get this stolen power back, simply go down to your
local hardware store and purchase a roll of refrigerator and
air conditioning insulation. Wrap all of your under-hood fuel
lines with the insulation to keep the cool in, and the hot out.
I read this on some web site, is it worth doing?

cooling the fuel may have a slight effect on the intake charge, but it will also make it harder for the fuel to burn efficiently.
I've actually heard pf people warming the fuel to help atomise it better and therefore get more complete combustion

Well it's pressurized AND stationary when you car isn't moving.. so in stop and go traffic it could make a diff.. but no more than the gas tank next to the exhaust.

I've heard of excessive heat soak into fuel lines causing vapor-lock. Might be an issue for those who have experienced hard starts after a long/hot run. But I haven't seen reports of no-starts in these conditions so maybe either the heat-soak is within bounds or the fuel pressure is high enough to overcome it.
