A: For Diesel diesel engines, replace the fuel filter every 15,000 miles or annually, whichever comes first. Severe-duty applications (towing, dusty conditions, high-idle time) should replace every 10,000 miles. Always replace both primary and secondary filters together. Q: What micron rating is the FM100? A: The FM100 features 30-micron filtration media, providing excellent protection for modern high-pressure common rail (HPCR) fuel injection systems while maintaining proper fuel flow rates. Q: What are symptoms of a clogged fuel filter? A: Symptoms include hard starting, rough idle, loss of power under load, engine stalling, poor fuel economy, and check engine light with low fuel pressure codes. If you experience any of these, check your fuel filter first it's the most common cause. Q: Do I need to prime the fuel system after replacing the filter? A: Yes. After replacing the FM100, you must prime the fuel system to purge air from the lines. Most Diesel engines have a manual primer pump on the filter housing. Cycle the primer until firm resistance is felt, then start the engine. Q: Is the FM100 compatible with ULSD and biodiesel? A: Yes, our fuel filters are compatible with Ultra-Low Sulfur Diesel (ULSD) and biodiesel blends up to B20. The filtration media and seal materials are specifically
