Source: Fleetguard Cross Reference by Part Number, doc LT19457D (2012). Fleetguard's published direction is manufacturer part → Fleetguard replacement.
Currentness: these crosses come from Fleetguard's 2012 list and have not been revalidated as current. Baldwin's 2024 list gives the same replacement for AF1781M and 22 of the 37 part numbers above. That shows a shared Baldwin replacement only. It does not verify that those numbers interchange with AF1781M today.
Upgrade chains run one way: equipment spec'd with a newer filter number should not step back to the older one. Go by what the truck was spec'd with.
Always verify against the current OEM catalog before ordering. Cross references are a starting point, not a guarantee of fit.
