Disconnect the connector from the fuel pump, then move the clips and disconnect the jet pump hose. Disconnect the quick connector, fuel delivery hose, and return hose. Remove the nuts that install the fuel pump assembly onto the fuel tank, and take off the fuel pump assembly.

The fuel pump is located inside the fuel tank

To replace the fuel pump in a 2002 Subaru Legacy L, you will first need to locate the fuel pump, which is inside the fuel tank.

• Pull back the carpet in the rear cargo area to expose the fuel tank.
• Locate the cover on top of the fuel tank, which is held down by four screws. Remove these screws and take off the cover.
• This will expose the fuel pump/sender unit assembly. You will know it's the fuel pump as it will have a white electrical connector and three rubber hoses attached to it.
• Purchase a replacement fuel pump. Ensure it is compatible with your 2002 Subaru Legacy L.
• Remove the old fuel pump/sender unit assembly and install the new one in its place.
• Secure the new fuel pump/sender unit assembly with the four screws.
• Place the carpet back in its original position in the rear cargo area.

By following these steps, you will be able to access and replace the fuel pump located inside the fuel tank of your 2002 Subaru Legacy L.

Disconnect the battery ground cable

Disconnecting the battery ground cable is a critical step when servicing your 2002 Subaru Legacy L. Here's a detailed guide on how to do it safely and effectively:

Safety First:

It's important to note that you should always disconnect the negative cable first. The negative terminal is typically marked with a "-" symbol or a black cover. Disconnecting the positive cable first can be dangerous. If you accidentally create a connection between the positive terminal and the car body while turning a wrench, it could result in a spark, fire, or even weld the wrench to the ground. So, always start with the negative cable.

Tools and Preparation:

Before you begin, make sure you have the necessary tools, such as a wrench or socket set to loosen the battery terminals, and protective gear like gloves and eye protection. Find a safe, flat workspace with good lighting and ensure you have enough room to work comfortably.

Step-by-Step Guide:

• Locate the Battery: Open the hood of your 2002 Subaru Legacy L and identify the battery. It is usually located in the engine bay, towards the front of the vehicle.
• Identify the Ground Cable: The ground cable is the thick black cable connected to the negative terminal of the battery. It is typically marked with a "-" symbol.
• Loosen the Cable Connection: Using your wrench or socket set, loosen the nut or bolt that secures the ground cable to the negative terminal. Be careful not to overtighten or damage the connection.
• Disconnect the Cable: Once the nut or bolt is loosened, carefully remove the ground cable from the negative terminal. You may need to wiggle it gently to detach it completely.
• Secure the Cable: After disconnecting the ground cable, make sure to secure it safely away from the battery to avoid accidental contact. You can use a cable tie or tape to hold it in place.
• Inspect the Cable and Terminal: With the cable disconnected, take this opportunity to inspect the condition of the cable and the terminal. Look for any signs of corrosion, damage, or wear. If the cable appears damaged or corroded, it may be a good idea to replace it.
• Clean the Terminal: If there is any corrosion or dirt on the negative terminal, use a wire brush to clean it gently. You can also apply a small amount of dielectric grease to help prevent future corrosion.

Remember to follow safety precautions and wear protective gear when working with your vehicle's electrical system. Ensure that you do not short-circuit any electrical components and always refer to a qualified mechanic or repair manual if you are unsure about any steps.

Drain the fuel from the tank

To drain the fuel from the tank of a 2002 Subaru Legacy L, first, lift the vehicle and remove the front side fuel tank cover. Place a container under the vehicle and remove the drain plug from the fuel tank. Tighten the fuel drain plug and install the front right side fuel tank cover.

Now, raise the rear seat and turn the floor mat up. Remove the access hole lid. Disconnect the connector from the fuel pump. Move the clips and then disconnect the jet pump hose.

This will allow you to drain the fuel from the tank of your 2002 Subaru Legacy L.

Disconnect the connector from the fuel pump

Disconnecting the connector from the fuel pump is a crucial step in accessing and replacing the fuel pump in your 2002 Subaru Legacy L. Here's a detailed guide on how to do this:

First, ensure you have located the fuel pump. In your Subaru Legacy L, the fuel pump is located inside the fuel tank and can be accessed through an opening at the top of the tank. To reach this point, you will need to pull back the carpet in the rear cargo area. You will see a cover held down with screws; remove this cover to expose the fuel pump assembly. The fuel pump itself will have a white electrical connector and three rubber hoses attached to it.

Once you have located the fuel pump, follow these steps to disconnect the connector:

• Move the clips that are holding the connector in place.
• Carefully disconnect the jet pump hose.
• Disconnect the quick connector.
• Now, you can proceed to disconnect the fuel delivery hose and the return hose. These hoses are labelled as "A" and "B," respectively.

By following these steps, you will have successfully disconnected the connector from the fuel pump in your 2002 Subaru Legacy L. Remember to work carefully and refer to a qualified mechanic or a repair manual if you need further clarification on any of these steps.

Remove the nuts that attach the fuel pump assembly to the tank

To remove the nuts that attach the fuel pump assembly to the tank, you will first need to lift the vehicle and remove the front side fuel tank cover. Next, place a container under the vehicle and remove the drain plug from the fuel tank. Once the fuel tank is drained, tighten the fuel drain plug and install the front right side fuel tank cover. Now, raise the rear seat and turn the floor mat up. You will then need to remove the access hole lid.

At this point, you can begin to disconnect components from the fuel pump. First, disconnect the connector from the fuel pump. Next, move the clips and disconnect the jet pump hose. Then, disconnect the quick connector, followed by the fuel delivery hose and the return hose.

After all the hoses and connectors have been disconnected, you can proceed to remove the nuts that attach the fuel pump assembly to the fuel tank. Keep in mind that you will need to remove the entire pump assembly from the tank before you can replace the fuel pump itself.
