The Baldwin Filters BF1278 is a spin-on fuel filter and water separator designed for diesel fuel systems. It targets fleet operators and heavy-equipment owners who need reliable contamination control during routine maintenance intervals.

Service life

The 40 micron rating captures coarse particles while the integrated drain lets technicians remove collected water without disassembly. An integral gasket seals the housing under continuous vibration and pressure cycling typical of commercial engine bays.

Fitment

Questions about this item

How much pressure drop should I expect from the 40 micron rating during continuous engine operation?

The 40 micron rating balances particle capture with flow; pressure drop stays low until the element loads with contaminant, then rises as the filter nears change interval.

Does the 1-12 thread size match the existing filter head on my equipment?

The filter uses a standard 1-12 thread; verify your filter head uses the same thread pitch and diameter before installation.

Will the 6 7/32 in height and 3 11/16 in diameter fit in the same bracket as my current spin-on filter?

Overall height is 6 7/32 in and outside diameter is 3 11/16 in; compare these dimensions to your bracket clearance and the filter being replaced.
