Alec, Thanks for the sticky link. I'll have to check and see if I even hooked up the fuel heater or if it is working. When the Cummins came to live in the Ford, I only remember hooking up the fuel solenoid, but looking at the wiring diagram I may have the heater hooked up as well. If I have the heater hoked up and no heat, it looks like a 2nd gen heater is in store for the Dord.

This is the first time I have replied on one of these discussions. I now live and work in south TX so don't have many issues with fuel jelling. According to the Chrysler Corp. service manual the fuel heater is located in the top of the fuel water separator adapter. The heater has a built in monitor that senses fuel temperature. Voltage to operate the fuel heater is supplied through the ignition switch. The heater operating range is from 6-13 C. 43-53 F.

If I lived somewhere that it gets colder that 60* like where I live, I would install a heater on my fuel filter canister to keep it warm and prevent it from gelling.

If the truck sits for extended periods you could power this from several solar panels on your dash.

8-amps @12-volts of solar power would supply 100 watts of continuous heat to the filter canister to keep it warmed and ready to go.

I would think just insulating the fuel filter canister would help improve cold weather drivability, think of the cold sheet metal fuel canister full of cold diesel being chilled by a constant blast of cold air from the cooling fan as it evaporates all of the heat out of the fuel.

Here are different versions of both mains and battery powered electric fuel heaters.

Also by warming your battery you can provide up to 60% more cranking amps.
A fully charged battery only produces 40% cranking power at 0* Fahrenheit.

Not colder than 60"????
How would it be??
The fuel filter heater is a good idea. Thanks for the input. Starting the truck has never been a problem, it is always about a mile or two down the road when the filter jells up.

Although I am envious of your weather, I'll take the traffic jam's (2 cars in front of you at the stop sign) and leaving the doors unlocked that a year round average of 38* seems to bring.

An insulator on the fuel filter canister itself...Hmmm never thought of that. Regardless if it's a heated unit or not, that is a good idea!
