Fleetguard LF721 cross reference

Baldwin lists PT87-S as the replacement for LF721.

Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). LF721 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.
