Probably would but I wouldn't do it. Better get it inside somewhere if at all possible and thaw it out. Then just put in a new one.
If you can't get inside get some diesel 911 and a new filter and try that..

If it runs, it will likely get starved for fuel. There's a pin at the top of the filter that releases the check valve in the stand pipe that allows full flow.
I sure wouldn't try to run w/o a filter unless it was an emergency - a call to AAA (or the tow company) is a lot cheaper than getting the injectors overhauled.

Thanks. That was what I was wondering. Someone told me it would run. I didn't beleive it. My bowl was very clean. So I tried it. It would barely run for 10 - 20 seconds. I put 911 in the canister with diesel and the rest in the tank. Wouldn't run even without the filter. Walked a mile and half at -17. Next day I got a new filter. Ran but filter light flickered and then came on solid. Went and got 5 gal. of #1. Then let it idle for 1 hour to use up the bad fuel. Runs good now. Must have gotten a bad blend.

Thats wild.. I havent heard too many here (actually any) having their fuel gel up this year! Might be suggestable to have a spare filter behind the seat!

Ya.I used to put Power Service treatment in when ever it got below zero. Then I started to trust the blending at the gas stations. I never learn. Long time ago I had a 6.2 that gelled up a couple times. Said to self " Not going to let that happen again." guess I just dropped the ball.

Don't think just a filter would have done it. The 911 took a while to work. The next day,when I put the new filter in the filter light came on in a mile or two. Think the fuel in the tank was to gelled. Once the I put the #1 in it cleared up.

I never got brave enough either in the PSD. My old 81 Jetta diesel's owners manuel said you could put up to 20% gas in, once I was stranded at -30 I put some in and it worked after about an hour of letting it idle. That's the only time I did it.
