This guide walks through the 6.4L’s dual-filter architecture, a step-by-step replacement procedure drawn from real-world video walkthroughs, the bleeding sequence that separates a clean start from a hydrolocked pump, and why the TruckTok replacement set is the smart money.
The 2008-2010 6.4L Powerstroke has two fatal vulnerabilities — fuel contamination kills the K16 pump, and fuel-diluted oil destroys the bearings. The fix for both problems costs $51.30 for a fuel & oil filter kit and takes about an hour in the driveway.

The guide covers the two-filter HFCM system, what actually gets the real cost of stretching past 15K and step-by-step DIY replacement.
