Baldwin BF7839 Fuel Filter

This Baldwin Filters BF7839 is a spin-on fuel filter designed for automotive and industrial plumbing systems. It uses a wound media element inside a threaded canister to capture contaminants before they reach the engine. The unit suits mechanics and fleet operators needing a direct replacement filter with a standard thread interface.

Filtration capacity and service limits

The filter element measures 4-25/32 inches in height and length with a width of 2-3/32 inches and an outside diameter of 2-27/32 inches. This physical envelope defines the dirt-holding capacity and flow resistance for the application. When the media saturates or the pressure differential exceeds the system limit, the filter must be replaced to maintain fuel delivery.

Threaded port, O-ring seal and mounting

The housing features an M36 x 1.5 port thread and a 3/4 in.-16 thread size for secure installation on compatible filter heads. Two O-rings are included to seal the mating surfaces and prevent fuel leaks under pressure. The spin-on design allows tool-assisted removal and installation without disconnecting hard plumbing lines.

Questions about this item

Will the 3/4 in.-16 thread and M36 x 1.5 port fit the existing fuel line on my older tractor?

The filter carries both a 3/4 in.-16 thread and an M36 x 1.5 port thread, so it matches many legacy tractor fuel lines that use either standard.

How can I confirm the BF7839 is sealing properly once installed?

After installation, prime the system and check for leaks at the two included O-rings and the threaded ports; a dry seal and steady fuel flow show it is working.

Does the box contain the O-rings or do I need to buy them separately?

Two O-rings are included with the spin-on filter, so no separate seal kit is required.
