One of the primary causes is water contamination in the fuel line. If the FS1242 filter is clogged or the water bowl is full, the fuel flow is restricted, leading to cavitation in the injection pump. Solution: Regularly drain the water-in-fuel bowl and replace the FS-1242 filter every 500 hours or as per your maintenance schedule to ensure the Cummins 6BT engine receives clean, dry fuel.
Common Issue: White smoke from the exhaust during acceleration?
This often indicates water is being burned in the combustion chamber. Replacing your current filter with a high-quality FS1242 Fuel Water Separator will solve this issue by intercepting water before it reaches the cylinders.
