Baldwin BF940 fuel filter

The Baldwin BF940 is a spin-on fuel filter designed to remove contaminants from diesel or gasoline systems. It installs directly onto a compatible filter head using M20-1.50 threads and an integral gasket for sealing. Fleet mechanics and equipment owners use it to protect injection components from abrasive particles.

Replaces worn filter elements

This unit replaces a spent spin-on cartridge when the service interval is reached or when fuel flow drops due to clogging. The jump is worth it when the old filter can no longer maintain the 15 micron rating, allowing finer debris to reach the pump. Regular change-outs keep fuel delivery consistent across the system.

Limited by thread and micron rating

The M20-1.50 thread size restricts fitment to heads with that exact pitch and diameter. The 15 micron media will not stop sub-micron water emulsions or the finest injector deposits that tighter ratings target. Physical envelope of 2 27/32 in height and 3 in outside diameter also dictates clearance in tight engine bays.
