I'm going to very, very respectfully disagree with putting the new style pump on. PEH has it exactly right, in my opinion; why not let the pump tell you which filter is at fault (especially on the road)? I think it's worth the drill to find the o-rings and possibly a junkyard pump to practice on.

Kyle, you may also want to consider a tow rope for the trunk, in addition to spare fuel filters. Pull starts are easy on a diesel and a lot easier on the battery. And someday you might be a hero to a young damsel in distress.
