What is the best method to keep the fuel system warm?
On my truck, I have had to change fuel filters several times this winter due to the filter getting so cold the water in the fuel turns to ice. I have also noticed a drop in fuel mileage and mo boss insists that I don't idle, so he has me use a plug-in heater when the temperature drops below 20. I did not have this problem last winter, as I was OTR regional most of the time and this year he has me running local.
I find that once I warm the filter or the truck (by pulling it into a heated shop or changing the filter), the truck runs fine until I fuel it or I park it overnight. He doesn't want me idling, because it costs him too much money in fuel expenses, and my fuel mileage has steadily dropped as the temperatures have gotten colder. Last night, it was 5 below zero, and one of my co-workers is having a very similar issue with his 2006 Volvo VN 630.
I am seriously interested in getting the FASS system and it's fuel filter heater for my truck, or perhaps getting a diesel-fired cab and engine heater (such as a Webasto). Which one would be better for our operation (hauling grain)?
Is this a good question?
