rbh, the glow plugs were replaced this summer when I redid the fuel lines, I normally do the cardboard thing right at the end of summer. One thing I did forget to do is the cetane and the fuel that is in the rig, was put in a year ago in October, there is about a 1/2 tank of that left then I have 10 gallons that I just purchased last month, so it should be winter blend. There are a couple of farm stores around here that should start selling red diesel winter blend anytime, so that is what I will pick up when available as this truck is not driven on the county roads, I am not subject to the fuel taxes. Like I said, was wondering if anyone was using the water circulating heaters, seems that would be a good idea to keep the coolant warm and moving a bit when it gets like this.
One thing with this truck, it is difficult to know how much fuel is really in it, the gauge works, but it is a Centurion conversion and has the flatbed on it, so they put a 35 gallon cube tank on the underside of the drivers side and I just found out, that tank is plumbed into the factory front rail tank, so if that is the case, those two tanks could be up to almost 60 gallons of fuel, then you have the rear tank, which I never put fuel in and have blocked the line as it has a couple of pin holes in it, so don't use it.
