Saw this question on another post and figured I'd post the # for the "warm weather" fuel filter for 00-01 trucks.
There are 2 filter choices, the standard -FS19579- thats good for all weather and another one -FS1261- thats good to around 15 degrees and warmer I believe. The 1261 is about 6 dollars cheaper than the standard filter and uses only different seals. My truck never sees temps this cold so I use the 'warm' one, Cummins NW pointed it out to me last trip in.
