Baldwin BF7997 Spin-On Fuel Filter

This Baldwin BF7997 is a spin-on fuel filter designed for fuel-system maintenance on compatible engines. It carries a 4 micron rating to capture fine contaminants before they reach injectors. The unit includes an integral gasket for a direct seal at installation. It suits technicians and owners performing scheduled filter changes.

M18 x 1.50 Thread Limits Fitment

The filter mounts on an M18 x 1.50 thread, so it only fits housings or heads cut to that exact pitch. A different thread diameter or pitch will prevent sealing and cannot be adapted safely. The 4 micron media sets a fixed filtration limit; finer or coarser requirements need a different cartridge. Clearance must accommodate the 8-5/32 in height and 3-23/32 in diameter.

4 Micron Rating Decides Suitability

The single specification that decides fitment is the 4 micron rating combined with the M18 x 1.50 thread. If the engine manufacturer specifies a different micron grade or thread size, this filter will not meet the fuel-cleanliness target or seal correctly. Buyers who need a different micron rating or thread pattern must select another part number.

Questions about this item

Should I choose the BF7997 or another Baldwin fuel filter with a different micron rating?

Choose the BF7997 when your engine requires 4 micron filtration. Select a different Baldwin model if the service manual specifies a coarser or finer rating for your application.

What does the 4 micron rating mean once the filter is installed?

It means the filter media traps particles 4 microns and larger, protecting injectors and pumps from fine contaminants that pass through coarser elements.

Will the M18-1.50 thread fit my fuel manager head?

Yes, if the filter head is tapped M18 x 1.50. The spin-on base seals against the integral gasket when hand-tightened plus the specified turn.
