Replacing Fuel Pump In Saturn Vue: Step-By-Step Guide

Replacing the fuel pump on a 2002 Saturn Vue is a complex job that requires advanced knowledge of automotive repair, specifically in fuel and exhaust systems. The fuel pump is located inside the fuel tank, and to replace it, the tank must be removed from the vehicle. This involves disconnecting various parts, including the EVAP canister vent and fresh air hoses, fuel pipes, and the fuel tank electrical connector. Once the tank is removed, the fuel pump locking ring can be lubricated and removed, and the fuel pump can be taken out. The process is then reversed to reinstall the new fuel pump, and the engine is started to check for leaks.

Disconnect EVAP canister vent and fresh air hoses

Disconnecting the EVAP canister vent and fresh air hoses is a crucial step when replacing the fuel pump on a 2002 Saturn Vue. Here is a detailed, step-by-step guide on how to do it:

First, locate the quick-connect fitting. Grasp both sides of the fitting and twist the female connector a quarter turn in each direction. This motion helps loosen any dirt or debris within the quick-connect fitting. Next, use compressed air to blow out any remaining dirt or residue from the fitting. This step ensures that the connection is clear of any obstructions.

Now, you can proceed to squeeze the plastic retainer release tabs. By doing this, you will be able to pull the connection apart. Once the connection is separated, take the time to inspect both ends of the quick-connect fitting for any remaining dirt or burrs. It is important to ensure that the connection is clean and free of debris before proceeding.

After inspecting and cleaning the connection, you can remove the EVAP vent hose and fresh air hose from the fuel tank. This step is crucial, as it directly impacts the fuel pump replacement process. It is important to exercise caution when handling fuel lines. Always place fuel in an approved container with an opening of at least 300 mm (12 inches) in diameter to adequately catch any spilled fuel.

By following these steps, you will successfully disconnect the EVAP canister vent and fresh air hoses on your 2002 Saturn Vue, allowing you to proceed with the fuel pump replacement process. Remember to reverse these steps when reinstalling the fuel pump to ensure a proper connection.

Disconnect fuel supply line from the fuel filter

Disconnecting the fuel supply line from the fuel filter of a 2002 Saturn Vue is a delicate process that requires careful attention to safety. Here is a detailed, step-by-step guide:

Step 1: Before beginning any work on the fuel system, it is crucial to relieve the fuel system pressure. This step is essential to prevent any accidental release of pressurized fuel, which could be dangerous. Refer to the "Fuel System Pressure Relief" procedure in your repair manual for specific instructions on how to safely relieve the pressure.

Step 2: Disconnect the negative battery cable. This step is important to prevent any accidental electrical sparks or shorts, which could be hazardous when working with flammable fuels.

Step 3: Raise the vehicle using a hoist or jack stands to gain access to the underbody of the car, where the fuel filter is located. Ensure that the vehicle is securely supported and squarely positioned to avoid any accidental movement or instability.

Step 4: Locate the fuel filter. In a 2002 Saturn Vue, the fuel filter is typically found on the left side of the fuel tank.

Step 5: Place a shop cloth or rag around the fuel line fittings to catch any spilled fuel. Have an approved fuel container ready to collect any fuel that may spill during the disconnection process.

Step 6: Disconnect the fuel inlet line and return line from the fuel filter. This step may require gently squeezing the top and bottom of the fuel line connector and pulling to release the connection. Be cautious, as the fuel lines may still be pressurized, even after performing the pressure relief step.

Step 7: Remove the fuel filter from its bracket by unscrewing the fuel filter bracket screw. This will free the fuel filter, allowing you to replace it with a new one.

Step 8: Install a new fuel filter by sliding it into the bracket and securing it with the screw. Ensure that the fuel lines are properly connected and secured with new plastic retainers.

Step 9: Reattach the negative battery cable and lower the vehicle from the hoist or jack stands.

Remember to work cautiously and refer to the repair manual for specific instructions and safety precautions when working on the fuel system of your 2002 Saturn Vue.

Disconnect fuel tank electrical connector

Disconnecting the fuel tank electrical connector is an important step in replacing the fuel pump of a 2002 Saturn Vue. Here is a detailed, step-by-step guide on how to do this:

Firstly, locate the electrical connector. This should be found near the fuel tank, underneath the car. It is important to note that the fuel tank is located inside the vehicle's gas tank.

Once you have located the electrical connector, you will need to disconnect it. This process should be done with care to avoid any damage to the surrounding components. Ensure that you are wearing appropriate protective gear, such as gloves and eye protection.

To disconnect the electrical connector, first, identify the bolt that secures it in place. This bolt can be removed using a 12 mm socket wrench. Once the bolt is removed, gently pull the connector apart. It is important to be gentle during this step to avoid damaging the connector or any surrounding components.

After the electrical connector is disconnected, set it aside in a safe place. It is important to keep the workspace organized and free of any debris to avoid any accidental damage.

At this point, you should also disconnect the fuel supply line from the fuel filter and the fuel tank ground strap fastener. These components are located near the electrical connector and can be disconnected using appropriate tools, such as wrenches or sockets.

By following these steps, you will successfully disconnect the fuel tank electrical connector and can proceed with the next steps in replacing the fuel pump of your 2002 Saturn Vue. Remember to refer to a qualified mechanic or a detailed repair manual for further guidance if needed.

Remove fuel pump from tank

To remove the fuel pump from the tank of a 2002 Saturn Vue, you must first relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Then, disconnect the fuel tank. Disconnect the fuel pump's electrical connector, fuel lines, and hoses. Remove the retaining ring for the fuel pump with wrench SA9156E and disconnect the retaining clip by pulling it toward the float arm and lifting up. Finally, lift the fuel pump out of the fuel tank and discard the old fuel tank seal.

Reinstall the new fuel pump

To reinstall the new fuel pump on your 2002 Saturn Vue, follow these steps:

First, you will need to prepare your vehicle for fuel pump servicing. Relieve the fuel system pressure by removing the fuel cap to equalize the pressure in the fuel tank. Next, disconnect the negative battery cable with a socket wrench. Then, disconnect the fuel tank by removing the rubber exhaust hangers, propeller shaft guard, and propeller shaft (if equipped).

Now, you can begin the process of installing the new fuel pump. Place the new fuel pump into the fuel tank, ensuring that it is secure and properly aligned. Reattach the fuel lines and hoses to the new fuel pump, as well as any reusable brackets and pick-up screens. Be sure to replace the fuel tank seal and install the lock ring on the fuel pump using the appropriate tool (SA9156E for the 2002 Saturn Vue).

Once the new fuel pump is in place, reconnect the electrical connections and hoses to the fuel pump, including the EVAP system hoses and the fuel tank electrical connector. Reattach the fuel tank to the vehicle and tighten the fuel tank strap bolts.

Finally, refill the fuel tank and reconnect the negative battery cable. Start your vehicle to check for any leaks and ensure that the new fuel pump is functioning properly.

It is important to note that you should always exercise caution when working with fuel and ensure that the work area is well-ventilated. If you are uncomfortable or unfamiliar with any of these steps, it is recommended to consult a qualified mechanic.
