* Primary Fuel Filter: This is located on the frame rail, typically near the fuel tank. It's a larger filter.
* Secondary Fuel Filter (Water Separator): This is also located on the frame rail, often near the primary filter, but sometimes a little further away. It's designed to remove water from the fuel.
To be absolutely certain of their location, I strongly recommend:
* Consulting your owner's manual: This will have diagrams and specific locations for your vehicle.
* Using a repair manual specific to your 2006 F-250 diesel: These manuals provide detailed diagrams and instructions.
* Searching online for "2006 Ford F250 diesel fuel filter location" with images: Pictures from other owners can be very helpful.
Without knowing the specific engine (6.0L Powerstroke, etc.), precise location can vary slightly. Using your vehicle's information will help you find the most accurate depiction of where your fuel filters are.
