Hi, New member and new duramax/allison owner. With winter coming on, what is the first thing I need to do to my 2002 2500? I've already ordered Primrose 409. From what I've read in the forums, secondary fuel filter may be next. Any suggestions on a secondary filter system?

This is the biggest one I've seen! It's the one that comes in the Nicktane kit (not shown).
