Safety First!
* Disconnect the battery: This is paramount to prevent accidental sparks.
* Work in a well-ventilated area: Fuel vapors are extremely flammable and dangerous.
* Wear safety glasses and gloves: Protect yourself from potential injuries.
* Use jack stands: Never work under a car supported only by a jack.
* Have a fire extinguisher readily available: Be prepared for any unforeseen circumstances.
General Steps (Consult your repair manual for specifics):
1. Prepare the Vehicle: Safely raise the vehicle using jack stands. Consult your owner's manual or a repair manual for proper jack points.
2. Disconnect the Fuel Lines:
* Locate the fuel lines: These typically connect to the tank at the rear of the vehicle.
* Relieve pressure: There may be a pressure relief valve or method to release pressure in the fuel system. This is vital to prevent fuel spillage. Your repair manual will guide you on this.
* Disconnect the lines: Use fuel line disconnect tools to carefully disconnect the lines. Have rags ready to absorb any spilled fuel.
* Plug the lines: After disconnecting, immediately plug the open ends of the fuel lines to prevent fuel leakage and vapor escape.
3. Disconnect the Fuel Sender: This unit measures fuel level and is usually wired to the gauge. Disconnect the electrical connector carefully.
4. Disconnect the Evaporative Emission System (EVAP) Lines: These lines are part of the emissions control system. Disconnect them carefully and plug them if necessary.
5. Disconnect the Filler Neck: This connects the fuel tank to the filler opening. This might involve removing clamps and possibly bolts.
6. Remove the Fuel Tank Straps/Holders: These straps secure the fuel tank to the vehicle. There are usually several bolts or fasteners involved. This may require loosening or removing some surrounding components to access the fasteners.
7. Lower the Fuel Tank: Carefully lower the fuel tank. It might be heavy and awkward, so have a helper if possible. Support the tank as you lower it to prevent damage.
8. Complete Removal: Once the straps and connections are removed, the tank should come free.
Reinstallation: Reinstallation is essentially the reverse of removal. Ensure all connections are secure and properly tightened. Have someone help you lift and secure the tank.
Important Notes:
* Year-Specific Variations: The exact location and access points for the fuel tank, straps, and lines will vary significantly depending on the year of your Firebird. Your repair manual is essential.
* Fuel System Diagram: A diagram of your specific fuel system will be incredibly helpful.
* Fuel Line Material: Be aware that fuel lines can be brittle and prone to cracking. Handle them gently.
* Professional Help: If you're not comfortable performing this task, consider taking your Firebird to a qualified mechanic. Working with fuel systems is dangerous and requires expertise.
Remember, safety is paramount. Consult your repair manual and take necessary precautions. Improperly handling fuel can lead to serious injury or even death.
