Welp, it finally happened... fuel iced up at -15 F. Got about 2 miles from home and watched the fp guage bounce aroudn then go to zero. About a minute later, coasted into a Sunoco/Dunkin Donuts. Six hours waiting for a hook. While waiting I tried a new filter, Diesel 911, and a propane torch... Couldnt get the fuel even to flow to the filter. It was not a bad six hour wait as the female sights going into and out of the place were superb. Back home a salamander heater got to work on the undersides, whiel I removed the water seperator (FASS system). Finally got fuel to actually flow at 9pm. Seemed OK today.
