For this procedure, you’d require gloves, a new OEM fuel filter, and a 32 mm socket wrench. Note that Ford 6.7 Powerstroke consists of two sealed cartridge fuel filters. The primary filter is found in the middle of the chassis at a lower position in the car. You can easily locate this alongside the frame rail on the driver’s side. The second fuel filter is located at the top portion of the engine. 

  • Spot the primary filter 

Your first step would be to locate the primary filter. It is situated at the bottom of the truck. It can be easily spotted alongside the frame rail on the driver’s side. The wire harnesses might offer some obstruction to the proper positioning of the main filter.

  • Drain the fluid 

Once the main filter is positioned along the frame rail on the driver’s side, you can then disconnect the fluid sensor. This would save it from getting damaged by fuel or water. The fluid can be adequately drained by placing an empty jar beneath the valve.

  • Remove the housing 

You can conveniently remove the filter housing with the help of a 32 mm socket wrench. This should take 5-6 turns. Sometimes the filter comes out along with the housing.

  • Carefully clean the housing

Once you have removed the housing, you must clean it. All mud and debris must be removed with the help of a clean cloth. All the grooves that hold the screws must also be carefully cleaned.

  • Replace the O-ring

Each filter comes with an O-ring. The old O-ring must be replaced with a new one. It is important to ensure that it fits correctly. 

  • Set the new filter 

The fresh fuel filter should be carefully inserted along with a clean housing. The entire unit must be turned until it tightens adequately. Screwing with a wrench is not recommended as it might break the filter or the housing. Then you must reconnect the fuel sensor and the water sensor to complete the installation. 

  • Locate the secondary fuel filter

Once you have located the secondary fuel filter at the top of the engine, you must disconnect the double fuel line above it. To disconnect the line, you’ll need to press the tabs at the lower portion of the clamp. Then you pull it upwards. 

This will drain fuel drops from the bottom of the line. To remove the second line, you can press the tabs on each side of the clamp and then pull the entire line out. 

  • Remove the filter 

After carefully disconnecting the fuel lines, you can turn the housing counterclockwise and remove the old filter. 

  • Install the fresh filter 

You can easily replace your previous filter with a new one. Your new filter will be positioned in the same cleaner housing and locked in place. You can push your fuel lines once this is done. 

  • Turn the key

Place your key inside the ignition and switch your truck on six times. This step is important because it removes any extra air. Missing this step could add air to the fuel components with high pressure. 

  • Check settings

You can confirm the installation of the new filter by checking your settings. It will go as settings-vehicle-maintenance-fuel filter-ok. There should also be a notification.
