Baldwin BF46039-D Cartridge

This Baldwin BF46039-D cartridge serves as a primary fuel/water separator element with an integrated drain. It fits diesel fuel systems that require a can-type filter to remove water and contaminants before they reach the engine.

Attached Grommet Benefit

The cartridge includes an attached grommet that simplifies installation by providing a ready-to-seal interface. This eliminates the need to source or fit a separate sealing component during routine filter changes.

Can-Type Build and Ports

The can-type construction uses a 3/4 in inlet and a 3 15/32 in outlet within a 7 3/4 in tall housing. Builders needing a different port arrangement or a spin-on style will need an alternative filter design.

Questions about this item

How often should the BF46039-D cartridge be replaced?

Replace the cartridge at the interval specified by the engine or equipment manufacturer; the BF46039-D is a primary fuel/water separator element with a drain for scheduled service.

What limits continuous flow through the 3/4 in inlet and 3 15/32 in outlet?

The can-type housing and attached grommet seal set the practical flow limit; sustained operation beyond the engine's rated fuel demand will cause pressure drop across the element.

Does the separator generate noticeable heat or noise during all-day operation?

The BF46039-D is a passive filter cartridge with no moving parts, so it produces no noise and adds negligible heat to the fuel system.
