Exploring Fuel Pump Replacement: 2008 Explorer Guide

Replacing the fuel pump in a 2008 Ford Explorer can be a moderately complicated job, but with the right tools and experience, it is possible to do it yourself. The fuel pump is located inside the fuel tank, and while most fuel pumps will last for the life of the vehicle, they can occasionally fail. Signs of failure include a car that won't start or stalls after starting, a slowly starving fuel flow causing the check engine light to come on, or a whirring sound coming from the fuel tank.

There are two main methods for replacing the fuel pump: dropping the tank or cutting an access panel. Dropping the tank involves lowering the fuel tank and removing the old fuel pump assembly, while cutting an access panel involves creating a hole in the floor of the vehicle to access the fuel pump without removing the tank. Both methods require disconnecting the fuel tank and fuel pump assembly from various hoses, clamps, and electrical connectors.

It is recommended to use a high-quality replacement fuel pump that matches or exceeds OEM standards and to have the work done by a qualified mechanic or dealership service department.

Disconnect the driveshaft

Disconnecting the driveshaft is a crucial step in accessing and replacing the fuel pump in a 2008 Ford Explorer. Here is a detailed, step-by-step guide on how to safely disconnect the driveshaft:

Before beginning, ensure you have the necessary tools, including a 12-point socket and an extension, as well as a floor jack and wood or a transmission jack to support the vehicle. It is also recommended to have some experience with car repairs.

First, put the vehicle in neutral and use a long screwdriver to keep the driveshaft from turning. You can use a little Kroil to make this step easier. Next, disconnect the large vent line at the rear of the vehicle, where it connects to the valve. There is another line at the back that you will also need to disconnect.

Now, position the jack under the middle of the fuel tank to support it. Once the tank is secure, remove the front and rear straps by removing the bolts. You will then be able to move the straps sideways, and the key that fits into the frame will allow the strap to come free.

At this point, you can start to lower the tank. It will mostly swing down at the back, giving you access to the lines and connections at the top of the tank. Use long-handled heater hose pliers to push the button on the top of the connectors down to disconnect them. Reach above the tank and disconnect the electrical connector by pushing in on the tab on one side.

With these steps completed, you have successfully disconnected the driveshaft and can now access the fuel pump for replacement. Remember to work safely and securely, and always refer to a trusted repair manual or a mechanic if you are unsure about any steps.

Remove the fuel tank

To remove the fuel tank from a 2008 Ford Explorer, you will need to perform the following steps:

Firstly, drain as much fuel as possible from the tank. This can be done by removing the filler neck hose and inserting a drain hose connected to a fuel caddy with a pump to pump out the fuel. Get the fuel tank down to a couple of gallons, so it is easier to manage.

Next, disconnect the fuel filter lines at the front end of the tank. Remember to relieve the fuel pressure. You will also need to disconnect the filler hose and a couple of vent lines at the rear. Be careful when removing the plastic fitting connectors. There is one on the rear that you need to press to expand and remove from the tank. This can be seen and accessed through the right rear wheel well with the wheel removed, or with the tank partially lowered.

Loosen the left side of the transmission crossmember, the two centre transmission nuts, and remove the right-side bolts. Lower the crossmember about three inches. Support the tank with a floor jack and a piece of wood to spread the load.

Two straps hold the tank in place, so remove these bolts and then remove the straps completely. Now, lower the tank a little and disconnect the remaining lines and electrical connectors. You may need to jack the tank back towards level to get it to move to the rear. Pull the tank, with the jack rolling, until the front of the tank is clear of the crossmember. Then, drop the jack and slide the tank out the back of the vehicle.

Finally, hose down the tank, as it will be covered in dust that you don't want entering the tank.

Disconnect the fuel filler hose

Disconnecting the fuel filler hose is a crucial step in replacing the fuel pump of a 2008 Ford Explorer. Here is a detailed, step-by-step guide on how to do it:

Step 1: Before beginning any work on your vehicle, it is important to ensure your safety. Make sure the car is parked on a level surface, engage the parking brake, and block the wheels to prevent accidental movement. Wear protective gear, such as gloves and eye protection, to safeguard against any potential hazards.

Step 2: Locate the fuel filler hose. It is usually found near the rear of the vehicle, connected to the fuel tank. The hose is responsible for delivering fuel from the gas cap to the fuel tank.

Step 3: Place a clean bucket or container under the fuel filler hose to catch any spilled fuel. Even a small amount of gasoline can be harmful to the environment, so it is important to contain any spills.

Step 4: Using the appropriate tool, such as a wrench or pliers, carefully loosen and remove the clamp that secures the fuel filler hose to the fuel tank. Some vehicles may have multiple clamps, so ensure all are removed.

Step 5: Gently pull the fuel filler hose away from the fuel tank. It may be connected to the tank with a rubber grommet or seal, so use a gentle back-and-forth motion to detach it without damaging the surrounding components.

Step 6: Once the hose is removed, place it aside in a safe location. You may want to label or mark the hose to ensure proper reconnection during the reassembly process.

Step 7: Inspect the fuel filler hose for any signs of damage, cracks, or leaks. If the hose is damaged, it is recommended to replace it with a new one to prevent fuel leaks and ensure the proper functioning of your vehicle.

Step 8: If you are unable to easily access the fuel filler hose or if it is stuck, you may need to raise the vehicle or remove additional components for better access. Always refer to a trusted repair manual or seek advice from a qualified mechanic if you are unsure about any steps.

Remember, working on a fuel system can be dangerous due to the presence of flammable liquids and pressurized components. Always exercise caution and refer to manufacturer guidelines or seek professional assistance if needed.

Disconnect the fuel filter

Disconnecting the fuel filter on a 2008 Ford Explorer can be a tricky process, but with the right tools and precautions, it can be done safely and effectively. Here is a step-by-step guide to help you through the process:

Step 1: Prepare the Vehicle

Before beginning any work, ensure your safety by putting on protective eyewear and gloves. Locate the fuel filter, which is situated near the gas tank under the car on the cross member, behind the passenger seat. To access it, you will need to remove a silver-colored metal shield. Place a clean bucket under the vehicle to catch any fuel that may spill during the process.

Step 2: Relieve Pressure in the Fuel Line

To relieve pressure in the fuel line, pull the fuel pump solenoid and attempt to start the engine. Be cautious, as fuel may come out. This step is crucial for your safety and to prevent any accidental spillage.
