Fleetguard HF6681 cross reference

Baldwin lists BT371-10 as the replacement for HF6681.

Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). HF6681 is newer than Fleetguard's last published cross-reference index (2012), so no Fleetguard-published crosses are shown.

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.
