get the car in a garage that is warmer than the gel point, Power service makes a product called Diesel 911 that suposedly ungels fuels ( i have never used it) or wait for it to warm up where the car is sitting.

there is a chart somewhere that shows the gel points at a certian blend. some one will come up with it and i will continue to search

*edit

It has a higher gel point. B100 (100% biodiesel) gets slushy a little under 32°F. But B20 (20% biodiesel, 80% regular diesel - more commonly available than B100) has a gel point of -15°F. Like regular diesel, the gel point can be lowered further with additives such as kerosene (blended into winter diesel in cold-weather areas).
