Here is a quick video on the process of changing the fuel filters on your 6.4 Powerstroke. I have changed the filters on this truck 3 times in the past 33,000 miles. I changed them once immediately upon purchasing it, and again 10,000 miles later. The 10,000 mile interval seemed a bit premature as the filters were still very clean. I decided to take this set to 20,000 miles, and they were definitely due for replacement, however they were not clogged or heavily restricted. Please Subscribe!
