Negative ten degrees in Laramie WY tonight, what do I got to do to keep from freezing?

I fueled in Rapid City yday and knew id probably be in Billings overnight (If my sphincter held out) and the temps were forecast for -12f ish.

I put Howes in just to be safe partly because the Crapcadias will NOT idle up. 600 at rest... 700 at full bump.

I've not been able to find any literature in the things stating definitively that they do , or do not, have any type of heated fuel return lines to aid in frigid temps.

I'm glad I put it in because when I got rolling it dipped to -31 around Livingston and stayed there for awhile.

That's chilly on my Willy.

If anyone knows about the fuel heat return lines I'd appreciate an educated response.

 

My 09 Cascadia high idles at 1000. Pretty sure it's an ECM setting.

 

The fuel is heated by the process of getting pulled up by the motor and returned unused. I'm pretty sure all truck motors do this. If you happen to have a Davco fuel filter, the clear globe, it can be hooked up to the coolant loop as well.

 

The fuel is heated by running across the top of the engine. The truck brings in more fuel then it can use. The unused fuel is sent back to the tanks. However the newer engines don’t return very much fuel ....but your always better off to let it run when it’s well below zero.

An acert cat returns like a gallon a minute at hwy speeds.......

 

Gelling fuel isn't my biggest concern, the issue that gets me most frequently is water in the fuel. I try to keep my tanks topped off and fill with #1 diesel whenever traveling north of I-70.

The problem is that small amount of water in the fuel. As soon as the fuel hits that super cold filter paper in the primary fuel filter, it freezes. Soon the entire surface is coated in a thin layer of ice and very little fuel gets through.

I've had to change fuel filters a few times each winter. Carry a set of spare filters, a GOOD filter wrench (NOT made of aluminum), a gallon mix of 70% diesel, 20% Howe's Antigel, and 10% Diesel 9-1-1, and some large garbage bags for disposing the old filter.

 

Must trucks do not have heated fuel tanks, that's an option only the guys that run in the extreme far north spec.

What people in this thread are talking anout is how the fuel is heated by the engine before returning to the tank. it pumps much more fuel to the injectors than gets burnt, that fuel warms as it passes through the fuel rail and the excess fuel is returned to the tank.

 

the uneducated will always assume they must leave the truck engine running you know how long it takes for your diesel to gel up? You could safely leave your engine off for at least 1/2 an hour if not more it just depends on how quickly it gets cold in your cab or how much warm gear you have on always be prepared for emergencies like this cause when you do run out of fuel guess whats going to happen? Learn from this experience and always come prepared with lots of stuff to keep you well fed for at least 3-5 days.

 

I would never turn my truck off below zero temperature away from home. Safe or not. Too many items can mechanically break in that cold.
