Safety First!
* Disconnect the battery's negative terminal. This prevents accidental sparks.
* Work in a well-ventilated area. Fuel vapors are highly flammable.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Never smoke near the fuel system.
General Steps (Year and Model Specific Details Will Vary):
1. Identify the Fuel Pump Location: The fuel pump's location varies depending on the year of your Firebird. It's often located inside the fuel tank (in-tank) or mounted on the chassis (external). Consult your repair manual to determine the location and access method.
2. Drain the Fuel Tank (If In-Tank): If the pump is in the tank, you'll need to siphon or drain most of the fuel from the tank. This significantly reduces the risk of spillage and makes the job safer.
3. Remove the Fuel Tank (If Necessary): Accessing the in-tank pump usually requires dropping the fuel tank. This involves disconnecting fuel lines, electrical connectors, and possibly the fuel tank straps. Support the tank carefully to prevent damage.
4. Disconnect the Fuel Lines: Carefully disconnect the fuel supply and return lines using appropriate fuel line wrenches or disconnect tools. Have rags or containers ready to catch any spilled fuel.
5. Disconnect the Electrical Connector: Unplug the electrical connector leading to the fuel pump.
6. Remove the Old Fuel Pump: The method for removing the old pump depends on its type and location. You may need special tools to remove it from the tank or from its mounting bracket.
7. Install the New Fuel Pump: Carefully install the new fuel pump, ensuring it is seated correctly. If it's an in-tank pump, pay close attention to the sealing gasket or O-rings to prevent fuel leaks.
8. Reconnect Everything: Reconnect the electrical connector, fuel lines, and any other components you disconnected. Double-check all connections for tightness and proper seating.
9. Lower the Fuel Tank (If Necessary): Carefully lower the fuel tank back into its position, securing it with the straps.
10. Reconnect the Battery: Reconnect the negative battery terminal.
11. Prime the Fuel System (If Necessary): Some vehicles require priming the fuel system after a pump replacement. This might involve turning the ignition key on and off several times or using a special priming tool. Your repair manual will provide details.
12. Check for Leaks: Carefully inspect all connections for leaks. Start the engine and look for fuel leaks around the pump and fuel lines.
13. Test Drive: After ensuring everything is leak-free, take the Firebird for a short test drive to verify that the new fuel pump is functioning correctly.
Important Considerations:
* Fuel Pump Type: Ensure you purchase the correct fuel pump for your specific Firebird year and model. There are different flow rates and electrical requirements.
* Tools: You will need various tools, including wrenches, sockets, screwdrivers, fuel line disconnect tools, and possibly a fuel tank support.
* Repair Manual: A factory service manual is essential for detailed instructions and diagrams.
