Baldwin BF1389-O Fuel Filter Spin-On

The Baldwin BF1389-O is a spin-on fuel filter designed for fuel and water separation. It features an open port for a bowl and includes a furnished gasket with an integral post seal. The thread size is 1 in.-14 and the bowl thread is 3 3/4-10 2B buttress.

Suits diesel systems needing a replaceable spin

This filter suits applications that require a spin-on fuel and water separator with an open bowl port. It is not for buyers who need a closed-port design or a different thread specification. Systems requiring a non-spin-on cartridge style should look elsewhere.

Verify thread size and bowl port before ordering

Confirm that your housing accepts a 1 in.-14 thread and a 3 3/4-10 2B buttress bowl thread. Check that the open-port configuration matches your existing bowl assembly. Ensure the gasket and integral post seal are compatible with your mounting surface.

Questions about this item

What thread size must my fuel line have to accept the BF1389-O?

The filter uses a 1 In. -14 thread, so your line or adapter must match that specification.

Will the 3 3/4-10 2B buttress bowl thread fit the separator bowl I already use?

Yes, if your existing bowl has the same 3 3/4-10 2B buttress thread it will screw on directly.

How can I confirm the spin-on filter is sealed correctly after installation?

Check that the furnished gasket and integral post seal are seated and that no fuel leaks appear at the 1 In. -14 thread or bowl port.
