Fuel Cooler

[Mike L.]

I wonder if a fan would help.. since the cooler is in kind of a weird place... thoughts?

Fan won't help a stock cooler. Been tried.

I thought someone told me that if your fuel temps get too hot it will throw a code. I just took his word for it never did any research.

When the fuel temp hits 230* it will start reducing fuel pressure to 165MPa.
By the time the fuel temp is at 239* the fuel pressure is reduced to 90MPa.

Pulling a trailer on a 100F day up a grade will do that.

So who has the best aftermarket fuel cooler to remedy this?

You have to build your own.

Seems like there would be a market for this.

I did what Jason did,put a cooler in front of stack, it cool fuel after stock filter setup

I need to see this and take notes next weekend Ruben, I want to do this since my fuel filter is right behind my headlight.

Anywhere in the 1/4 area they will really jump, on a hot enough day and if you run and work the truck long enough it will do it. Hot fuel can cause low rail codes too!

The lower it is in fuel tank the less of cool fuel in there to cool the returning heated fuel. If you have a lot of cool fuel already in the tank, it will help the heated returning heated fuel acclimate to the lower temp of the fuel that's there. The less there is in the tank then,,,,,,

I have seen trucks with fuel temps in the 230s, running a truck low on fuel seems to increas temps especially when towing in warm weather!

thanks a bunch guys! :thumb: I should probably not run her so low. I think CTS monitors fuel temp. need to find out
