Today in Massachusetts it -5 degrees. Went outside and started the truck. Let her warm up for 20 mins. Running like a champ. Fuel pressure reads 0 psi. Went through the diagnosis found the fass fuel pump fuse was blown. Replaced the fuse got my fuel pressure back. I couldn't believe how well the truck was running just off the injection pump. Without the fuel pressure gauge u would never know the difference. I would have been driving around with no lift pump, till it blew up the vp44.  Wondering why the fass blew the fuse, thick fuel? Everyone needs a fuel pressure gauge with these trucks. 

Had mine down to -20f a month ago with a fass and no fuel heater plus I forgot to plug the truck in. But on a side note I have also poped my fass fuse before it is around 10 below when I did it ran inside to the gas station came out and had zero pressure. Changed the fuse and down the road I went.you have to have a fuel pressure  Guage. I get funny looks when I tell ppl that I have a fuel pressure  gauges  in the truck

You folks in extreme cold,  can you use heat tape for plumbing but instead placed along your fuel lines and plug it in at night?

I thought but doing something like this a few years ago when I was having a lot of gelling issues. The way I look at it is you'll have nice warm fuel to start the engine but the 30 gallons of frozen goo in your tank will cancel that out in short order. 

Unless you got something like this

I went with these and haven't gelled a filter since:

Nice to see this kind of post since most are typically because of a problem! I drove mine on a 1000 mile trip and put on a gauge on it right after only to find out I had 0 pressure the whole time!  Really drives home the importance of a fuel pressure gauge on these trucks!

Was the Vp fine still after this ?
