Been there, done that. Thats why I alwasy run blends after about Halloween. It can be quite the inconvience.

You likely have a solid tank and fuel lines as well. When I was working at the diesel shop, we had many rigs get towed in with the same problem. You generally have to change fuel filters, and get as much diesel in as possible to get it started in the near future. If you have the time you can wait until the temps warm up again, but it has to heat up quite a bit before all the gelling will go away.
