Fleetguard AB15803 cross reference

Baldwin's 2024 catalog lists BT40015 as the replacement for AB15803.

Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). AB15803 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.
