Baldwin BF5816 Fuel Filter Overview

The Baldwin BF5816 is a high-efficiency secondary fuel filter designed for spin-on installation. It carries a 4 micron rating to capture fine contaminants and protect downstream injection components. The unit includes an integral gasket and integral post seal for reliable sealing without separate parts. It fits applications requiring a 13/16 in.-12 thread size.

Suitable Applications and Limits

This filter suits diesel systems that specify a 4 micron secondary spin-on element with the given thread and dimensions. It is not for buyers who need a different micron rating, a different thread pitch, or a primary filter with water-separation capability. Systems requiring a larger or smaller canister diameter should look at other models.

Capacity and Service Life

The 4 micron media provides fine filtration for clean fuel delivery to high-pressure pumps and injectors. Service intervals depend on fuel quality and operating conditions; the filter runs out of capacity when restriction reaches the engine manufacturer's change limit. The compact 7 3/32 in height allows installation in tight engine compartments where longer canisters will not fit.

Highlights

  • 4 micron rating traps fine contaminants
  • Spin-on design enables quick replacement
  • Integral gasket and post seal prevent leaks
  • 13/16-12 thread fits compatible fuel systems
  • High-efficiency secondary filtration protects injectors

Questions about this item

What thread size must the existing filter head have to accept the BF5816 spin-on fuel filter?

The filter uses a 13/16 In. -12 thread, so the filter head must match that thread specification for proper installation.

Can the BF5816 be used as a secondary fuel filter in a system that already has a primary filter with a coarser micron rating?

Yes, this is a high-efficiency secondary fuel spin-on rated at 4 micron, designed to work downstream of a primary filter.

How can I confirm the BF5816 is sealing correctly after installation?

Check for fuel leaks at the integral gasket and integral post seal once the engine is running and the system is pressurised.
