NAPA LLY Fuel Filter

[Shire Ben]

What is correct NAPA fuel filter for 2004.5 LLY.
Diesel truck service company changed it with 3810 @ 15K and replaced it with 3910 today @ 30K...is this an improved filter?? Thank You

The new filter is most likely the updated filter which has a dual element media. John Kennedy has some very nice pictures of the new filter on his web site. http://www.kennedydiesel.com/ :eek:
