Cold truck is a cranky truck.
This morning the outside air temp was -8. Started my truck and it run for 2 or 3 mins before driving off. About 2 miles in to my trip I get low fuel pressure/reduced engine power message. I turned around and limped home at 6mph. I’m assuming fuel gelling? I need to make a 180 mile trip tomorrow. Any suggestions on what I can do to make this truck work by tomorrow AM?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

The general theme lately on the 6.7 forums is fuel related, it seems. It's almost becoming the #1 concern for owners here. Low fuel pressure, fuel filters, water in fuel, cetane rating, lubricity rating, additives and demulsifiers...
My truck was cold when I started it today and it did the warm up countdown. But that was about as exciting as it got.
From what I understand, the excess fuel return to the tank helps warm up the fuel somewhat, so in that case apart from moving the vehicle to a warmer place, you would just have to continue running the vehicle because if you let it sit, it will just cool down again.

911 and a small heater pointed at the fuel filiter has her back running. Temps are coming up in to the teens.

I wouldn't use the 911 stuff unless there is just no other option. The 911 formula contains alcohol which will bond with and carry any water in the system directly to the HPFP and the injectors. A better option in this situation would be a healthy dose of the white bottle Diesel Kleen and let the truck idle to circulate the fuel. As long as it runs at all, I wouldn't take a chance on the alcohol containing emergency formulas!

Diesel 911 contains an EMULSIFIER that can and will carry water straight past the fuel/water separator and into the HPFP!
I would NEVER use this stuff on a 6.4L or 6.7L truck. The cost of the damage could well pay for 100+ tows!
Get it? NEVER!!!
I think I may make a stickie out of this...

Truck said -27c outside. Didn't sound the best starting and was a hair rough but fired on 2 nd crank.
Immediately jumped to 1150 rpm and counted down for 22 secs before it said was ok to drive.
10 mins at high idle has my oil at 20C.
