5. FAQ - Troubleshooting & Search-Driven Solutions

Question: Why is my 6CT engine losing power and showing a "Water in Fuel" light?
Answer: This is often caused by a saturated fuel water separator. When the FS1280 filter reaches its water holding capacity, it restricts flow. Replacing the filter immediately prevents water from reaching the fuel injectors, which can cause corrosion and expensive repairs.
Question: How often should I replace the FS 1280 filter on a standby generator?
Answer: For generators, we recommend replacement every 250-500 hours or annually, whichever comes first. Fuel degradation in storage tanks makes a high-quality separator like the FS1280 essential.
Question: Why Choose This Fuel Water Separator?
Answer: Our filters feature an OEM-standard tri-metal structure and high-grade media. They are Trusted by repair shops and equipment fleets worldwide for their reliability and perfect fitment.
