Baldwin BF863 Fuel Filter 25 Micron

The Baldwin BF863 is a spin-on primary fuel filter rated at 25 microns. It features a removal nut for easier service and includes a G401 integral gasket. The unit measures 4 11/16 inches in height and length with a 3 11/16 inch outside diameter.

Diesel mechanics and fleet technicians

This filter suits technicians who need a standard 25 micron primary fuel filter with a 13/16-18 thread and removal nut. It is not intended for applications requiring finer micron ratings or water separation capabilities. Systems with different thread specifications will not accept this filter.

Thread size 13/16-18 determines fit

The 13/16 inch -18 thread size is the critical specification for compatibility with the fuel filter head. Verify this thread specification against the engine or filter housing requirements before installation. The included G401 gasket seals against the mounting surface.

Questions about this item

How can I confirm the BF863 filter is working correctly after installation?

Start the engine and check that fuel flows through the spin-on housing without leaks at the 13/16 in.-18 thread; the 25 micron rating will then trap contaminants as designed.

What comes with the BF863 and what must I source separately?

The box includes the spin-on filter with the G401 integral gasket and removal nut; you will need to supply the matching 13/16 in.-18 mounting head and fresh fuel.

Which micron rating should I choose for this Baldwin filter?

This model is offered only in a 25 micron rating, so select the BF863 when your system calls for 25 micron primary fuel filtration.
