FAQ
Q: What micron rating do I need for my diesel fuel filter?
A: Most OEMs spec 10-micron for the primary (frame-mounted) water separator and 4-5 micron for the secondary (engine bay) filter. For CP4.2-equipped trucks (2011+ Ford 6.7L, 2011-2016 Duramax LML), many owners upgrade to 5-micron primary for extra pump protection.
Q: How often should I change my diesel fuel filter?
A: Every 15,000 miles or per your owner's manual. If you fuel at questionable stations or run biodiesel, change every 10,000 miles. Always drain the water separator bowl at every oil change.
