I believe that the fuel in the truck has gelled and now the truck won't start. I had added anti-gel and everything was fine down to about 20F, but we had a couple of days of below zero temps and now the truck is a no-go.
Here's the basics:
Truck cranks fine, just won't fire up.
I've added Diesel 911 to both the tank and the fuel filter bowl.
Truck has sat with Diesel 911 in it for 2 days
Last two days temps reached the low 40's
I have been running the engine heater for a few hours each day
Drained the fuel bowl and changed the filter.
Now when I try to crank it, the fuel bowl won't even fill. (Doesn't matter which tank, front or rear, I try to use.)
Is there another common inline filter that I am missing?
Where could the problem be?
Additional notes: The diesel I buy is supposed to be winterized, but I don't trust them, so I always add antigel from diesel power services.
Also I believe that many of the local stations maybe running 10% biodiesel as I have seen several stations suddenly add HANDWRITTEN signs stating 10% Biodiesel. I've heard rumors that diesel additives and biodiesel should not mix and can gel. So I'm worried I picked up some biodiesel unknowingly.
Any help would be greatly appreciated as I have to report for duty in one week and really need my truck to start.
I'm guesing it's your lines. There was a guy in Iowa that tried to unfreeze his lines by starting a fire underneath. You can guess how that worked out for him. You can do that or try to get it inside or otherwise warm. It should be well above freezing there today.

I would be willing to bet a penny its no gelled. It doesn't happen very often but I your fuel pump may have gone out. Generally the fuel pump just starts to leak and they still pump fuel but it has happened a few times. Leave the lid off the filter housing and with a blow gun and rap cover the filler neck and try to push fuel up to the filter housing. if it goes you need a fuel pump.
I'll also try using a hairdryer on the lines to warm them up.
Anyone have any other suggestions?
Yeah, a heat gun. Concentrate on the two steel lines that run from the tank switching valve forward.
For an extreme gelling issue you could disconnect the tiny fuel hose that's at the top of the steel line (of course this is the supply line not the return) that connects to the fuel pump then after you have applied heat to the tube, put compressed air down the filler neck of the tank that the switch is on. You'll need a rag to create a seal. The air will blow out anything in the line. To avoid a diesel mess in the engine bay, attach a hose to the steel line and have it drop into a bucket.

I will test and see if the pump is bad. If it is, is there any trick to pulling the old pump and not draining the tanks out the disconnected hoses?
The fuel pump (lift pump) sits in the valley right behind the fuel filter canister. You don't need to drain the tanks. If you want an excellent article by Sam Miller on how to replace the fuel pump just send me a PM with your email address and I'll send you a copy.
I stumbled across the Miller article last night and it is great. So I am giving the pump a shot tonight.
One question, how likely is the push rod to fall back down the engine? One site mentioned loosening the pump (but leaving the bolts still in) and crank the engine until the cam is "up" thereby minimizing the chance of dropping the push rod. Good idea or no?
Yeah most likely it's not gelled, however i did think of one solution if it were gelled fuel lines. You could wrap them with an electric pipe heater, just make sure it's not touching anything that would melt. Easy Heat Electric Water Pipe Freeze Protection Cable.
