Safety First:
* Disconnect the negative battery terminal before starting any work. This is crucial to prevent sparks and electrical shock.
* Work in a well-ventilated area. Fuel fumes are flammable and dangerous.
* Wear safety glasses and gloves.
Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Torque wrench
* Fuel line disconnect tools (or pliers, but use caution to avoid damage)
* Screwdrivers (Phillips and flathead)
* Jack and jack stands (essential for safety)
* Wheel chocks
* Fuel pump pliers (highly recommended)
* New fuel pump assembly (ensure it's the correct part number for your vehicle)
* Shop rags
* Safety glasses and gloves
* Possibly a fuel pressure gauge (to verify the pump's function after installation)
Steps (General Outline):
1. Preparation: Consult a repair manual specific to your 1997 Buick Regal GS Supercharged. This will provide detailed diagrams and torque specifications crucial for a successful repair. These manuals are available online or at auto parts stores. Locate the fuel pump access panel, typically under the rear seat or in the trunk. Raise and securely support the vehicle on jack stands.
2. Access the Fuel Pump: This often involves removing parts such as the rear seat (if the access is under the seat) or interior panels in the trunk.
3. Disconnect Fuel Lines and Electrical Connectors: Carefully disconnect the fuel lines using the appropriate fuel line disconnect tools. Have rags ready to soak up any spilled fuel. Disconnect the electrical connector to the fuel pump. Note the position and routing of the lines before disconnecting to aid reassembly.
4. Remove the Fuel Pump Assembly: The fuel pump is usually held in place by a retaining ring or clamp. You might need fuel pump pliers to remove the retaining ring. Carefully remove the assembly, taking note of how it's assembled. The entire assembly, including the strainer, should be replaced in most cases.
5. Install the New Fuel Pump Assembly: Carefully install the new fuel pump assembly, ensuring it's seated correctly and the strainer is properly positioned. Reattach the retaining ring or clamp.
6. Reconnect Fuel Lines and Electrical Connectors: Reconnect the fuel lines and electrical connector, ensuring a tight and secure connection.
7. Reassemble: Reinstall any panels or components removed earlier.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Check for Leaks: Carefully inspect all connections for leaks.
10. Start the Engine and Check Fuel Pressure (Optional but Recommended): Start the engine and check for any fuel leaks. If you have a fuel pressure gauge, use it to check the fuel pressure to ensure the pump is working correctly.
Important Considerations:
* Fuel Pressure: After installation, the fuel system may need to be primed. This often involves cycling the ignition key several times before attempting to start the engine.
* Correct Part Number: Use the correct fuel pump assembly part number for your specific vehicle to ensure proper fit and function.
* Repair Manual: A repair manual is absolutely vital. The steps and details above are a general overview; your specific vehicle may have slight variations.
* Professional Help: If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
