Each emissions step changed the fuel system architecture enough to require a different filter spec. The 2012 truck and the 2018 truck and the 2024 truck all have \"MX-13\" on the valve cover. None of them takes the same fuel filter. A fleet running Kenworth T680s of different model years owns four filter inventories, not one, and ordering the wrong one for the wrong year is the most common parts-counter mistake on this engine.\u003c\/p\u003e\n\u003cp\u003eSteinberg stocks 11 SKUs across the MX-13's lifetime: FF034 for 2010-2014, FF033 for 2015-2017, FF020 fuel filter kit for EPA17+ (2017+), FF016 fuel filter kit for EPA21 (2021+), FF031 water separator for 2015-2022, FF032 fuel filter for 2016+, FF014 water separator cross-fit Cummins X15 housings, FF007 multi-make separator, FO003 oil filter for EPA17+, and the FA001\/FA002 air filters that fit Kenworth and Peterbilt cabs housing these engines. Each is cross-referenced to PACCAR K37-series and Fleetguard FF, FS, and LF part numbers and ships same-day from Hodgkins, IL. NET-30 terms for qualified fleet accounts.
