fuel cooler?

pullingtrucker i was looking through my jegs, and summit cataloges they have several some with a fan mounted on them cool...............

 

Yeah I was looking at their catalogs. I'm planning on stopping by Summints Talmage, OH store to look at the coolers first hand here in about a month.

 

Most trucks don't have coolers, and really don't need them. Most of the cooling actually comes from air blowing over the fuel tanks while driving. You can certainly add one. I would route a cooler at the front of the rad by using a P/S or tranny cooler. The fuel will still heat up once it enters the head the cost of installing this probably greatly out weights the minor benefit you would see if any. Trucks that need and benefit from coolers are mainly off-road, construction type trucks such as dump trucks or garbage trucks that don't get the cooling effect from highway driving.

 

I disagree, cool fuel can mean half a gear better off on hills and I would think it would be better for the injectors.
All the Western Stars have them over here fitted from the factory I shifted mine to get better cooling.

 

I also believe a feul cooler is a very good idea and I have used them on all my trucks.Go feel your feul tanks after running down the road a while they get really hot.It may not be much of a factor during the winter but in the summer it can be a big help.You just have to be sure to install the cooler where it will get good airflow.Just a thought, if cooler feul wasn't a benifit,fooling the ECM(with a resistor) to think the feul is hot would not work.The engine manufacturers know that hot feul does not make as much power as cool feul so they compensate for it.About the theory of cooling the feul with wind blowing by the feul tanks....wonder how well that works on the tupperware trucks with all the side skirts on them?Likely not too well.One last thing,all of the OEM feul coolers I have seen are the same as the air to oil trans. coolers.

 

The newer motors certainly do need coolers. They have messed with the time so much that the motors are running very hot. Which in turns heats the fuel up to the point that it airates (I know its spelled wrong) and also starts to harm the injectors. The cooler you can get the fuel the better. Yes the fuel will heat up again when it enters the head, but it will not be as hot as it would normally be. Also this cooler fuel that isn't injected will be able to carry more heat away from the motor and into the tanks. Cooler fuel is denser than heated fuel which in turn means that the cooler fuel will have more injected into the motor on every cycle compared to heated fuel.

 

FWIW, Cat says 86 degrees is perfect fuel temp. compromise between power and economy
