1. Safety First: Disconnect the negative battery cable to prevent electrical shock and accidents. Engage the parking brake and chock the wheels if you are performing this task on an incline.
2. Locate the Fuel Tank: In a 1996 Buick Century, the fuel tank is generally located under the rear of the vehicle.
3. Remove the Fuel Filler Cap: Open the fuel filler door and remove the fuel filler cap to allow any built-up pressure in the tank to escape safely.
4. Disconnect Fuel Lines: Underneath the vehicle, locate the fuel lines that are connected to the fuel tank. Disconnect these fuel lines carefully, being ready to catch any spilling fuel.
5. Disconnect Electrical Connections: Disconnect any electrical connectors or wiring harnesses connected to the fuel tank or fuel pump.
6. Remove Tank Support: There may be straps, bolts, or brackets that hold the fuel tank in place. Remove these components to carefully lower the fuel tank.
7. Lower the Fuel Tank: Use a floor jack or support to lower the fuel tank carefully. Make sure to place a cloth or cardboard underneath to protect the tank and prevent damage.
8. Remove Fuel Pump Assembly: Once the fuel tank is lowered, you will have access to the top of the tank where the fuel pump assembly is located. Remove any bolts, clamps, or connectors holding the pump in place.
9. Replace Fuel Pump: Remove the old fuel pump and install the new one, ensuring that all connections are secure. Be mindful of the fuel pump gasket or seal to prevent fuel leakage.
10. Reinstall Fuel Tank: Carefully lift and reinstall the fuel tank, ensuring the proper positioning of all its supports. Reconnect the fuel lines, electrical connections, and fuel filler cap.
11. Reconnect the Battery: Reconnect the negative battery cable to restore power to the vehicle.
Remember, this is a general guide, and the exact steps may vary depending on your specific vehicle. Always refer to your vehicle's service manual or consult with a professional mechanic if you are not confident in performing these tasks.
