One gallon of hot fuel contains fewer BTUs than a gallon of cold fuel. For that reason an engine is more efficient when cool fuel enters the cylinder. IMO cool fuel should result in better MPG. I am sure someone else can give a better answer.

Update

It will put more fuel thru the engine but if the engine becomes more efficient and mileage should come up.

I have used air to air trans. coolers for fuel since 1997 as per the advice of a CAT mechanic. Cooled fuel helps prolong the life of injectors. It also definitely improves performance. On a hot day here in GA the truck runs as well at 4 in the afternoon as it did when the temp. was much lower in the early morning. The difference is very noticeable between the hot days of summer and 20-30- degree days in NY. One word of caution: bypass the cooler in the winter so that your fuel won't gel easily. On a Paccar prod. the cooler is very easy to mount in front of the radiator with dealer supplied brackets.

i doubt that it matters since it combusts when compressed, in the cylinder, which raises the air/fuel mixture temp.

Fuel coolers are common on race cars and cooler air is more dense and makes more power so you would figure that it would help. I have a Bud that took a transmission cooler and runs his return fuel through it. He also installed a fan on the cooler and hooked it to a switch on the dash, seems to be working well for him. Thinking about doing the same thing myself......

both you and Your are right when it comes to cooler fuel making more power but won't that also increase the amount of fuel burnt?
