Gel points of fuel

This came from a truck mag I was reading at work.

Biodiesel fuel can start clouding up at temperatures between 30 and 50 degrees depending on the blend. Straight ULSD fuel may begin to gel up at temperatures between 20 and 32 degrees. However No. 1 ULSD, also called ULSD K because of the kerosene content, decreases the gel point for cold weather driving. By comparrison the old untreated low-sulfer fuel was stable down to temps of around 0 degrees.

I know that we took fuel to a truck on the road the other night when it was -10 and the little we slopped on the containers didn't run more than abouit 2 inches and stopped... Not a good sign.

My 06 manual show a graph to use winter blended fuel (50/50 mix of #1 & #2 diesel) at 20 degrees and colder. I've heard from several people that ULSD will gel between 22-25 degrees so I never take a chance and use anti gel any time I think the temp will drop below 25 degrees above zero.

The first time I dumped ULS fuel into my truck it was about 22 degress outside. I had gelled fuel indications when I restarted up the truck after fueling. I think the fuel was semi-frozen inside the gas stations fuel storage tank as it has been cold here for a while.

My truck still has gelled fuel indications (1 week latter). I haven't had the time to dump the fuel and clean the tank, or blast air into the tank. My fuel pressure starts out at 4 psi and raises to about 6 psi after driving around 15 miles.

Gelled fuel sucks. I have never had a problem with gelled fuel before.

XJJoe01,

What you need to do is pour a qt of PSD 911 (its in a Red qt bottle) in to your tank to de-gel the fuel and once its de-geled then add 16 oz or so of winter PSD (white bottle) as it has anti gel in it to keep your fuel from geling again.

On top of the ULSD problems add the Minnesota 2% bio.
During the cold snap (-25F) the distributors were blending 70% #1
Now that we're at +25F they are up to a 50/50 blend.
It appears to drop everything in the filter into a thick & gooey mess.
My Espar is normally very sensitive to clouded fuel from a very small fuel line. It hasn't missed a lick this winter which I attribute to no filter.
