Replacing Fuel Pump In 2008 Dodge Avenger: Step-By-Step Guide

The fuel pump in a 2008 Dodge Avenger is located inside the fuel tank. It delivers fuel to the engine, ensuring the vehicle runs smoothly. Fuel pump replacement costs can vary depending on location, but the average cost for a Dodge Avenger fuel pump replacement is between $738 and $775, with labour costs estimated between $79 and $99, and parts priced between $659 and $675.

Disconnect the battery

Disconnecting the battery is the first step in changing the fuel pump on a 2008 Dodge Avenger. This is done to reduce the chance of a fire. Here is a detailed, step-by-step guide on how to disconnect the battery:

Locate the battery – The battery is typically located in the engine bay, on the side or at the front of the engine compartment. It is a large, rectangular unit with two metal terminals protruding from the top.

Gather the necessary tools – You will need a basic tool kit, including a wrench or socket set to loosen and remove the battery cables. It is also recommended to wear safety gear, such as gloves and eye protection, to prevent any accidents.

Prepare the worksite – Before beginning any work, ensure that the car is parked on a level surface and engage the parking brake to prevent accidental movement. Make sure the engine is off, and if possible, remove the key from the ignition.

Loosen and remove the negative cable – Identify the negative battery cable, which is usually black and marked with a "-" symbol. Use the appropriate-sized wrench or socket to loosen the nut or bolt holding the cable to the battery terminal. Once it is loose, carefully lift the cable off the terminal. Ensure that the cable does not touch any metal parts of the car to avoid creating a short circuit.

Loosen and remove the positive cable – Locate the positive battery cable, typically red and marked with a "+" symbol. Again, use the correct size tool to loosen the nut or bolt securing the cable. Remove the cable from the terminal, being careful not to let it touch any metal surfaces that could cause a spark.

Secure the cables – After both cables are removed, place them in a safe location away from the battery and any metal components. Ensure they cannot accidentally fall back onto the battery terminals or create a short circuit.

Check the battery – Inspect the battery for any signs of damage, leaks, or corrosion. If there is any corrosion or buildup on the terminals, you can use a mixture of baking soda and water to clean them gently.

With the battery disconnected, you can now proceed to the next steps of changing the fuel pump on your 2008 Dodge Avenger. Remember to exercise caution and refer to a professional mechanic's guidance if you are unsure about any part of the process.

Remove the fuel tank access cover

To remove the fuel tank access cover of your 2008 Dodge Avenger, you will first need to disconnect the battery to reduce the chance of a fire.

Next, locate the fuel tank access cover. This will be inside the passenger compartment. Once you have located the access cover, remove it.

In some cases, you will need to drain the fuel before removing the access panel. This is an important step to avoid spilling fuel all over your car's interior. Make sure you have a suitable container to hand, and drain the fuel tank until the level is below the access panel.

With the cover off, you will be able to access the fuel pump and pre-pump filter screen. You can now proceed to replace the fuel pump.

Replace the pump and pre-pump filter screen

To replace the pump and pre-pump filter screen of a 2008 Dodge Avenger, you will need to purchase a new fuel pump that fits your car. You can find one at AutoZone, with prices starting from $19.99.

Once you have the new pump, the first step is to disconnect the battery to reduce the chance of a fire. For pumps inside the fuel tank, there will usually be an access cover that needs to be removed. With the cover off, you can replace the pump and pre-pump filter screen. In some cases, you will need to drain the fuel before removing the access panel.

If the pump is outside the tank, disconnect the fuel lines, remove the pump, and install the new one. Once the pump is replaced, check for fuel leaks to ensure there are no issues.

It is recommended that you replace the fuel filters at the same time as the fuel pump. Additionally, cleaning the fuel tank before installing a new pump can reduce the risk of contaminating the replacement pump.

Check for fuel leaks

Once you have replaced the fuel pump on your 2008 Dodge Avenger, it is important to check for fuel leaks. Fuel leaks are dangerous and can be caused by a variety of issues, such as a faulty fuel tank, fuel line, or fuel pump.

To check for fuel leaks, start by inspecting the fuel tank and fuel lines for any signs of leakage. Look for wet spots, drips, or puddles of fuel. If you notice any fuel odours, this could also indicate a leak.

If you have just replaced the fuel pump, it is important to check the work area for any signs of leakage. Use a flashlight to carefully inspect the area around the fuel pump, including the access panel and any fuel lines connected to the pump.

If you notice any fuel leaks, it is important to address the issue immediately. Do not start the car or drive it. Contact a professional mechanic or a repair shop to diagnose and fix the issue.

It is also recommended to regularly check for fuel leaks as part of your vehicle's maintenance routine. This will help ensure the safety and proper functioning of your car.

Clean the fuel tank

To clean the fuel tank of your 2008 Dodge Avenger, you will need to purchase a fuel tank cleaning kit. Delphi, the manufacturer of fuel pumps for Dodge Avengers, recommends the FFC01 kit. This will reduce the risk of contaminating the replacement pump.

Before you begin, make sure you are wearing the proper safety gear, including gloves and eye protection. You will also need a flathead screwdriver, a Phillips-head screwdriver, and a wrench.

Start by locating the fuel tank. It is usually found underneath the rear of the vehicle, near the exhaust system. Once you have located the tank, place a container underneath it to catch any fuel that may leak during the cleaning process.

Next, use the wrench to loosen and remove the fuel tank cap. Set the cap aside in a safe place. Look inside the tank and locate the fuel pump. It is usually located near the top of the tank and is connected to the fuel lines.

Using your screwdriver, carefully detach the fuel lines from the pump. You may need to use both the flathead and Phillips-head screwdrivers, depending on the type of screws used in your vehicle. Be careful not to drop any screws or debris into the fuel tank.

With the fuel lines detached, you can now remove the fuel pump from the tank. Set the pump aside and inspect it for any signs of damage or contamination. If the pump is damaged, you will need to replace it with a new one.

Use the cleaning kit to clean the inside of the fuel tank. Follow the instructions provided with the kit carefully. Make sure to clean all the surfaces of the tank, including the bottom and the sides.

Once the tank is clean, inspect it for any signs of damage or corrosion. If the tank is damaged, it will need to be repaired or replaced before installing the new fuel pump.

After cleaning and inspecting the tank, you can now install the new fuel pump. Carefully insert the pump into the tank and secure it in place. Reattach the fuel lines to the pump, tightening the screws securely but being careful not to over-tighten them.

Finally, reattach the fuel tank cap and tighten it securely. Start the vehicle and check for any leaks or issues. If there are no problems, your fuel tank and pump are now clean and ready for use.
