Changing the fuel filter is part of the repair and maintenance schedule for your Ford Explorer. The fuel filter is always located between the fuel tank and the engine, and for most vehicles, it is inside the top of the fuel tank. However, on some cars, it might be elsewhere along the fuel line. To maintain good performance, car companies recommend changing the fuel filter every 5 years/50,000 miles. The process of changing the fuel filter on a 2002 Ford Explorer involves relieving pressure in the fuel system, removing the heat shield and plastic cover, disconnecting the hoses, and installing a new filter.

What You'll Learn
Relieve fuel pressure
To relieve fuel pressure on a 2002 Ford Explorer, you must first open the hood and locate the relay box. This is the black box in the driver's side corner of the engine compartment. Next, locate fuse #23 and pull it out. Then, start your truck and let it run until it stalls.
You can also relieve the residual fuel pressure in the lines by pulling the fuse to the fuel pump and trying to start the truck. This will result in a hissing noise coming from the intake manifold, indicating that it is safe to remove the fuel lines.
Another method is to use a small device to depress the Schrader valve, which is located on the fuel rail on the passenger side towards the back. Be sure to place a rag around the valve when doing this to catch any gasoline that may spill or spray.
It is important to relieve fuel pressure before attempting to change the fuel filter, as this will prevent you from getting sprayed with gas and make it easier to remove the fuel lines without causing damage.

Remove heat shield and plastic cover
To remove the heat shield and plastic cover on a 2002 Ford Explorer, follow these steps:
First, locate the fuel filter. It is on the passenger side, in front of the fuel tank, and can be hard to see due to the heat shield and plastic cover. The heat shield is made of aluminum and is held in place by three 13mm bolts. To access the filter, you will need to remove both the heat shield and the plastic cover.
Before starting, ensure you have the necessary tools, such as a ratchet, 10mm socket, 13mm socket, Ford fuel tool, rags, safety glasses, and a new filter.
Now, to remove the heat shield:
- Loosen and remove the three 13mm bolts that hold the heat shield in place.
- Set the bolts aside in a safe place, as you will need them again when reassembling the components.
- Gently lift and remove the heat shield, being careful not to damage any surrounding components.
With the heat shield removed, you can now access the plastic cover:
- Using your hands or an appropriate tool, carefully detach the plastic cover from the fuel filter housing.
- Again, set the cover aside safely, as you will need it for reassembly.
With both the heat shield and plastic cover removed, you should now be able to see and access the fuel filter for replacement. Remember to refer to your owner's manual or seek professional guidance if you are unsure about any steps in the process.

Disconnect hose connections
Disconnecting the hose connections is a crucial step in removing the fuel filter on a 2002 Ford Explorer. Here's a detailed guide on how to do it:
First, relieve the fuel pressure in the system. Open the hood and locate the relay box, which is usually a black box in the driver's side corner of the engine compartment. Remove either relay #48 or fuse #26, as shown in the owner's manual. With the fuse or relay removed, start the Explorer and let it run out of fuel. Attempt to start it a few more times to ensure the fuel system is no longer pressurised.
Now, locate the fuel filter. It is typically found on the passenger side, in front of the fuel tank, under the passenger seat. There will be an aluminium heat shield and a plastic cover over the fuel filter, which you will need to remove.
Next, you will need to remove the hose connections. The output side of the filter has a metal clip that needs to be slid towards the filter and then pushed up to disengage. You will need to use a Ford tool to remove the output side hose. Place the tool over the filter tube and slide it under the hose connection. You may need to wiggle it a bit to release the internal spring and pop it apart.
The input side of the filter uses a different connector with a red plastic clip. Undo this clip, and then gently push the two ends up to release the filter.
Throughout this process, it is important to be cautious and prepared for any spilled fuel. It is recommended to have rags and safety glasses on hand to manage any spills and protect yourself. Remember to perform this task in a well-ventilated area to avoid inhaling fumes.

Remove the filter
To remove the fuel filter on a 2002 Ford Explorer, you must first relieve the fuel pressure by removing the fuel pump relay or fuse and starting the vehicle. The relay and fuse are located in the black relay box in the engine compartment on the driver's side. Once the vehicle has run out of fuel, attempt to start it a few more times to ensure the fuel system is no longer pressurised.
Next, locate the fuel filter. It is on the passenger side, in front of the fuel tank, underneath a plastic cover and an aluminium heat shield. To access the filter, remove the three 13mm bolts holding the heat shield in place, followed by the plastic cover.
Now you can see the filter, remove the hose connections. The output side has a metal clip that needs to be slid towards the filter and then pushed up to disengage. The input side has a red plastic clip that needs to be undone. Once both clips are removed, gently push the two ends up to release the filter.
Use a rubber mallet to tap the filter out—remember, this is a gas filter, so do not use a regular hammer. Place a block of wood between the mallet and the filter if necessary.
