    Are you sure that your filter base isn't heated? My Davco has coolant lines running through the base and a spot to plug it in if necessary. It doesn't take very much time at all before warm coolant gets into the base.

    If yours has the heat lines, it should have room for a heater also, If so, just need to replace one of the plugs in the bottom with a heater. Some are 120 volt and some are 12 volt. Oh, you will need to run a power to it from a switch if running on 12 volt.

    I have the preheater on my davco. though it is on only if key is on. you can turn key on & it will take just a few minutes to warm fuel. but it does nothing while key is off. another thing is, if truck is off & the fuel in the tanks gel, then the preheater wont help that.

    Gelling is very unlikely anymore. Since most truckstops mix #1 with the #2 fuel this time of the year. And gelling doesn't start normally until below 15 degress. The futher north you run the sooner and more the truck stops mix this fuel to prevent it from gelling at the pump. A rare way to get geling would be running up north on fuel you purchased down south.
    Also this mixing of fuel is the big reason we all get worse fuel economy in the winter.

    Flightline is right. I would add though, that one of the biggest problems is condensation in fuel tanks. Icing is probably the culprit more times than fuel gelling. The best way to reduce that risk is to top the tanks when possible before a time when the truck will be shut off for longer than a couple of hours. When fuel cools, it contracts and tanks that are not close to full will pull in a lot of moist air when that fuel contracts. Over time, water builds up in the tanks. Then you might have to reach for that Power Service 911 stuff and change out those filters. Not a good thing when the temp is below 0F and the wind is blowing at 30 mph. I try to top off the tanks each day during the real cold times. Not always practical, I will concede that. But the more you adhere to doing it, the better off you will be. An added plus to keeping tanks as full as possible.... it takes a lot longer for the warm fuel in a fairly full tank to cool than in a tank half full or less.

    And, as anyone at this game for any length of time will tell you, even the fuel islands at the truck stops can freeze up. If you keep your tanks as full as possible as often as you can, if you come across one of those truck stops that you can't get fuel at, you will not be left out in the cold. Pardon the pun.

    You should really do some research on the ULSD that is being sold nowadays. You might think twice before you say that about fuel gelling.

    Very Interesting and worth reading. Though I don't see it disagreeing with my comments but adding alot more.
    Fuel iceing and wax removing from the fuel around 0 degrees. But also stated non of the antiwaxing additives would help this problem.
    I think Cowpie has the best solution (keeping the tanks top off).
    I would like to point out that I haven't used any antigel additive in the last 10 years and have not had fuel gel in last 15 years. Also I try to stay south of Canada.
