I live in Idaho, and mine is broke, have not yet replaced it. It got down to about -26 below zero, and it takes a little more cranking to get the beast started, but not much more. I think that you should be fine. Just my 2 cents.

No heater here. I don't think the heater does anything for you because the fuel goes through the heater faster than the thing can heat it anyways, but that is just my $.02

hmmm well i think im gonna take it off, besides it probably just restricts the fuel more than anything thanks

Get rid of it.

I dont have any of my stock fuel system anymore. IMHO its the best thing I have done.

Alright dumb question. These trucks have fuel heaters on them or is this a aftermarket thing????

I removed mine when I installed the air dog wanted less restriction and direct feed to the ip. never a problem. and airdog says its fine ED

I removed mine and my truck runs fine in temps all the way down to 5 degrees F

What did everyone do with there WIF (water in fuel) sensor?

I switched to a racor 490R. You can get 200w electric heaters for the bowl as well as a WIF setup. Its different than stock so you need their kit with the lights and sender.

Well i got cummins filter heads and fleetguard filters for around 40 bucks. I think i am going to tap the cummins filter head for a WIF sensor and not worry about a heater.

My elec. connector melted on the fuel heater, removed the heater two years ago, on problems, oh sorry, no issues, I live in the northwest down to -0*. Not sure about the WIF light, it has nothing to do with the fuel heater.

Generally speaking, getting rid of the fuel heater is fine. However, just remove the heater part and don't remove the whole assembly because there is a prefilter screen in there that catches the big sediment.

The benefit of the fuel heater is that it can help keep your fuel filter from clogging due to gelling. When fuel gels, it gets wax crystals in it and these crystals clog up the filter media which eventually starves the engine of fuel. The problem with gelling is almost always at the fuel filter. My recommendation to people who have a working heater is to unplug it so that it doesn't burn up and cause an air leak. You can either unplug the plug that is a few inches from the heater or you can pull the relay. This way, if your fuel pressure starts to drop on a really cold day(meaning you are gelling), you can plug it back in and you will have a better chance of not gelling up.

My understanding is that the fuel heater will cycle even when the key is off. If above is true, that would aid in startup since warmer fuel is easier to ignite, easier to atomize into burnable molecules, and easier to inject so less stress on injection pump.

I used to have a temp gauge in my fuel and the during the cold winter months, a warm engine cycles enough extra fuel back to the tank that temp would be at least 45* even if it was 5 below zero cruising down the Montana freeway.

In the summer, I have seen 150* degree fuel!
