If you're not comfortable with advanced automotive repair, take your car to a qualified mechanic. This is strongly recommended.
However, if you are determined to proceed yourself, here's a general outline. Remember this is not a complete guide and may vary slightly depending on your specific vehicle's configuration. Always consult a repair manual specific to your 1995 Buick Riviera Supercharged for detailed instructions and torque specifications.
Safety Precautions:
* Disconnect the negative battery terminal before starting any work on the fuel system.
* Relieve fuel system pressure. This is crucial to avoid spraying fuel and causing a fire. Consult your repair manual for the proper procedure. It usually involves disconnecting a fuel pressure regulator line and cranking the engine for a few seconds.
* Work in a well-ventilated area. Fuel fumes are dangerous.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
General Steps (Simplified):
1. Access the Fuel Pump: This usually involves dropping the fuel tank. This requires removing the rear bumper and sometimes other components depending on access points. Your repair manual will have detailed instructions and diagrams for this step.
2. Disconnect Fuel Lines: Carefully disconnect the fuel supply and return lines. You'll likely need special fuel line disconnect tools to avoid damaging the lines. Have rags ready to absorb any spilled fuel.
3. Disconnect Electrical Connectors: Unplug the fuel pump electrical connector.
4. Remove the Fuel Pump Assembly: Once the lines and electrical connector are disconnected, you'll need to remove the access panel or cover to the fuel pump assembly inside the fuel tank. This may involve removing retaining straps or bolts.
5. Remove the Fuel Pump: The fuel pump is usually part of a larger assembly that includes the sending unit (which measures the fuel level). The entire assembly is often removed together.
6. Install the New Fuel Pump: Install the new fuel pump assembly, making sure it's seated correctly.
7. Reconnect Everything: Reassemble everything in the reverse order of removal, ensuring all connections are secure and tight. Pay close attention to the fuel lines and electrical connectors.
8. Lower the Fuel Tank: Carefully lower the fuel tank back into position.
9. Reconnect the Battery: Reconnect the negative battery terminal.
10. Check for Leaks: Check for fuel leaks around all connections.
11. Prime the Fuel System: After reconnecting the battery, you may need to prime the fuel system. Your repair manual will explain the proper procedure. This is usually done by turning the ignition key on and off several times to allow the pump to fill the fuel lines.
12. Start the Engine: Start the engine and check for proper operation.
Tools You'll Likely Need:
* Socket wrench set
* Wrenches
* Fuel line disconnect tools
* Safety glasses and gloves
* Jack and jack stands
* Fuel pump removal tool (may be required)
* Repair manual specific to your 1995 Buick Riviera Supercharged
This is a general overview and may not be entirely accurate for your specific vehicle. Refer to a repair manual for detailed instructions and torque specifications. Improper installation can lead to serious problems, so seeking professional help is strongly recommended. The cost of a professional repair might be less than the cost of a mistake.
