Replacing The Fuel Pump In A 2010 Forester: Step-By-Step Guide

Changing the fuel pump in a 2010 Subaru Forester is no easy task, but with the right tools and know-how, it can be done. The fuel pump is an essential component of your car, delivering fuel from the tank to the engine for combustion. When it fails, your engine may struggle to maintain speed, make unusual noises, or even overheat. While it's always best to consult a mechanic, if you're feeling adventurous, here's a brief overview of the steps to change your fuel pump. First, gather your tools and a replacement pump. Then, disconnect the battery and fuel lines, and remove the seats and trunk trim. Next, carefully remove the old pump assembly, taking note of the wiring and fuel line connections. Install the new pump, ensuring an airtight seal, and reconnect the fuel lines and wiring. Finally, reassemble the interior, reconnect the battery, and start the car, hoping for the best.

Disconnect the battery

Disconnecting the battery is one of the first steps to changing the fuel pump in a 2010 Subaru Forester. Here is a detailed, step-by-step guide to doing this safely and effectively:

Firstly, locate the battery. In the 2010 Subaru Forester, the battery is located in the engine bay, on the driver's side of the vehicle. It is typically held in place by a clamp or bracket, which you will need to remove in order to access the battery terminals.

Once you have located the battery, the next step is to disconnect the negative terminal first. This is an important safety precaution as it reduces the risk of electrical short circuits or accidental activation of the starter motor. Look for the negative terminal, which should be clearly marked with a '-' symbol or a black cover. Using a 10mm socket wrench, loosen the nut or bolt that secures the negative battery cable to the terminal. Be careful not to let the wrench touch any other metal parts of the car, as this could cause a short circuit. Once the nut or bolt is loose, carefully remove the cable from the terminal.

After the negative terminal is disconnected, move on to the positive terminal, which is marked with a '+' symbol or a red cover. Again, use the 10mm socket wrench to loosen the nut or bolt securing the cable. Remove the cable from the terminal, being mindful to avoid any contact with other metal components.

With both cables now disconnected, carefully move the battery out of the engine bay and place it in a safe location, away from any flammable materials. If the battery is heavy or cumbersome, you may need an assistant to help lift and carry it.

It is important to note that car batteries contain sulfuric acid, which can be dangerous if it comes into contact with skin, eyes, or clothing. Always wear protective gear, including gloves and eye protection, when handling a car battery. In the event of acid spillage, neutralize it immediately with a mixture of baking soda and water, and ensure you dispose of the spillage safely.

By following these steps, you can safely disconnect the battery in your 2010 Subaru Forester, allowing you to proceed with the fuel pump replacement or other maintenance tasks.

Remove seats and clutter from the trunk area

To remove the seats and clutter from the trunk area of a 2010 Subaru Forester, follow these steps:

First, clean out the trunk area of any clutter. This includes removing any personal items or debris that may be present. Next, you will need to remove the seats. For this step, you will need a 12mm socket wrench. Remove both the seat bottoms and the passenger-side section of the 60/40 split seat backs. Be sure to set the seats aside in a safe place to avoid damaging them.

Once the seats are removed, locate and remove the black styrofoam cubby located directly behind the seat backs. This will expose the area where the fuel pump is accessed. With the trunk area clear, you can now proceed with the next steps to access and replace the fuel pump. Remember to work safely and refer to a qualified mechanic if you are unsure about any part of the process.

It is also recommended to wear a respirator or breathing apparatus to avoid inhaling fumes during the fuel pump replacement process.

Disconnect fuel lines and clips

Disconnecting the fuel lines and clips is a crucial step in changing the fuel pump in a 2010 Subaru Forester. Here is a detailed guide on how to do this:

Firstly, ensure that you have the necessary tools and safety equipment. In this case, you will need a set of needlenose pliers and, for your safety, a respirator. It is also highly recommended to perform this task with an almost empty gas tank to reduce the risk of spillage.

Now, to begin disconnecting the fuel lines and clips:

• Remove the gas cap to relieve pressure in the tank.
• Locate the fuel lines and clips. They will be connected to the fuel pump, which is typically located inside the fuel tank.
• Before disconnecting anything, carefully observe the setup and take note of how the lines and clips are connected. This will be important when it comes to reconnecting everything later.
• Using the needlenose pliers, carefully disconnect the fuel lines from the fuel pump. Take your time with this step to avoid any damage to the lines or the pump.
• Once the fuel lines are disconnected, turn your attention to the clips. These clips help secure the fuel lines in place, so be sure to detach them carefully to avoid any accidental spills or leaks.
• As you remove each clip, place them in a safe location so that they can be easily accessed when it's time to reassemble everything.

At this point, the fuel lines and clips should be successfully disconnected, and you can proceed to the next steps of removing and replacing the fuel pump. Remember to work carefully and avoid any sparks or open flames during the process.

When it's time to reconnect the fuel lines and clips, refer to the notes you took earlier to ensure everything is connected correctly.

Replace the old pump and strainer bag

Now that you have removed the old pump assembly, it's time to install the new one. Place the new strainer bag and pump into the assembly, being careful not to bend the wire coat hanger-like component as this will affect your fuel gauge accuracy.

Next, you will need to use a new rubber gasket or clean the existing one thoroughly. It is also important to clean the access panel surround. You may want to use a sealant to create an airtight seal and prevent your CEL from illuminating.

Now, carefully finagle the whole assembly back into place. Tighten the nuts, being careful not to overtighten and break a stud. Reconnect the fuel lines and quick clips. You may choose to replace the quick clamps with hose clamps at this stage, as described in the previous step.

Finally, put the foam gasket and access panel back on, followed by the styrofoam cubby.

Reassemble and reconnect

Once you have the new pump in place, it's time to start reassembling and reconnecting everything.

First, make sure the float is in the correct position and that you haven't bent the wire coat hanger-looking thing, as this can affect your fuel gauge accuracy. Next, use a new rubber gasket or clean the existing one thoroughly. Clean the access panel surround, and consider using a sealant to create an airtight seal. Now, carefully put the whole assembly back into place, being careful not to bend or break any components. Tighten the nuts, but be careful not to overtighten and break a stud. Reconnect the fuel lines and quick clips. You may want to replace the quick clamps with hose clamps at this stage. Put the foam gasket and access panel back on, followed by the styrofoam cubby.

Now, it's time to put the seats back in. Reconnect the green clip under the dashboard, and reconnect the battery. Tighten the gas cap, and start the car. Hopefully, it works!

Some additional notes: it may be best to do this repair with an almost empty gas tank. Wear a respirator or breathing apparatus to avoid inhaling fumes. Take the time to vacuum and clean up any crud or debris from under the seats.
