Anyone Install a Fuel Cooler?

I really think you have change the way you drive, I have been using sea foam on all my vehicles and boats, lawn mowers, preasure washer etc ect for many years and unless theres a lot of carbon build up on an engine, there's no reason for better fuel mileage, sea foam has nothing to raise the btu of diesel fuel to give you a 1/2 mpg, but what ever you're doing keep doing it, sea foan will clean up carbon build up, so Im sure your piston tops are as clean as they were new.

 

This is a great idea and even with my truck I do not like to use over 150 gallons of my 300 gallon capacity tanks because the fuel returned heats up the fuel in the tanks to hurt fuel mileage. The lower the fuel in the tanks the easier it is to bring up the fuel temperture in the tanks with the returned hot fuel that hot fuel hurts fuel mileage.

 

My 2002 379 with C-15 500hp has on factory installed

 

Good idea! I'll maybe have one put on right before the injectors, and maybe one by the intakes on the tanks.

 

Years ago in NASCAR several got caught cheating by running the fuel lines through a coil inside an ice box filled with dry ice to cool the fuel for more HP that would equate to more efficiency with fuel mileage.

I did a google search to learn more recently it was caught by NASCAR in Jimmie Johnson's car...

Cooler fuel will give a bigger bang due to molecules are more dense.

Racing has all the experts we need to prove alot of things because they are always looking for more.

After running for about an hour the tire pressures are up higher for lower rolling resistance and the gallons of lubricants have thinned out making less resistance that may overcome the fuel getting hotter, but the idea would be to gain even more by cooling off the fuel even more for that gain that would be normally lost with hotter fuel.

Summit Racing sells alot of fuel coolers for the racers.... http://www.summitracing.com/search/Part-Type/Fuel-Coolers/

 

Got it planned out.
1. Fuel cooler on the intake line from the tank to the injectors.
2. Fuel cooler on the line past the filter that feeds the injectors.
3. Fuel cooler's on the return line right before the tank.

A lot of heat before those marked spots. I'm getting 8.4-8.7 MPG now... wonder how much it would get using fuel coolers?

 

What about winter in south dakota? Can you shut these coolers off? When it's -20 it's pretty nice to have all that warm fuel going back to the tanks. But what do I know, I don't get out much!

 

Maybe they have a fuse you can yank out. I have yet to take my new truck into Canada, but it has fuel heaters that are built-in. Temperature activated, I believe.

 

If you buy your fuel in Canada you don't really need to worry about it. We start running winter fuel in October. I have never used additives while running cdn fuel, even at -40 going across the prairies. US fuel is another story ...
