Baldwin BF7971-DM Fuel Filter

This Baldwin BF7971-DM is a cartridge-style fuel filter built for primary filtration on diesel and gasoline systems. It fits equipment that calls for a 7 11/32 inch tall element with a 3 5/16 inch outside diameter. The unit arrives new with an attached gasket and grommet so the sealing surface is ready at installation.

Cartridge Design with Removable Drain

The metal canister uses a spin-on style mounting thread that matches the original equipment housing. A removable drain plug at the base lets technicians purge collected water and sediment without removing the entire filter. The attached gasket stays seated during service, reducing the chance of a dry seal on reassembly.

Replaces Worn Primary Elements

This filter replaces a used primary element that has reached its service interval or shows pressure-drop symptoms such as hard starting or power loss. The jump is worth it when the old cartridge can no longer hold back fine particles or when water separation falls below spec. It is not for systems that require a secondary or final filter with a different micron rating.

Questions about this item

What thread standard does the BF7971-DM cartridge use for sealing?

The cartridge has no thread size; it seals with an attached gasket and grommet instead of a threaded connection.

What are the exact outside diameter and length the housing must accept?

The housing must accommodate a 3 5/16 in outside diameter and a 7 11/32 in overall length.

Which step is most often missed when fitting the BF7971-DM?

Installers frequently forget to remove the old grommet from the housing bore, causing the new cartridge to seat incorrectly.
