However, it's not a guaranteed location. Ford sometimes varied placement slightly depending on specific options and build configurations. The best way to be certain is to:
* Consult your owner's manual: This is the most reliable source.
* Look closely along the frame rail near the fuel tank: Start at the tank and follow the fuel lines. The filter will be inline with those lines.
* Use a repair manual specific to your year and model: A Haynes or Chilton manual will have diagrams and detailed instructions.
Don't be afraid to get under the truck and look carefully. The filter is usually a cylindrical canister, and might be marked with a fuel filter or fuel system label. Be cautious when working under the truck and use jack stands for safety.
