Here's a general overview of the steps, but this is not a substitute for a repair manual:
Safety First!
* Disconnect the battery negative terminal. This prevents accidental sparks.
* Work in a well-ventilated area. Gasoline fumes are highly flammable and dangerous.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
Steps (General Outline - Consult your repair manual for specifics):
1. Drain the fuel tank: This is critical. Use a siphon pump to carefully remove as much fuel as possible. Dispose of the fuel properly according to local regulations.
2. Disconnect the fuel lines: This requires careful handling. You'll likely need to use fuel line disconnect tools to safely separate the lines from the tank. Be prepared for some fuel spillage – use absorbent material to soak up any leaks. Mark the lines to ensure correct reassembly.
3. Disconnect the fuel sending unit: This is the unit that measures the fuel level. Disconnect the electrical connector and any other attached components.
4. Disconnect the EVAP (evaporative emission) system lines: These lines connect to the tank and prevent fuel vapors from escaping into the atmosphere. Disconnect them carefully.
5. Disconnect the vent line: This allows air to enter the tank as fuel is used.
6. Remove the fuel tank straps: These straps hold the tank in place. They may be bolted or use some type of retaining clip. You'll need to carefully loosen and remove these straps.
7. Lower the fuel tank: Carefully lower the tank. It may be heavy and awkward. You may need a helper. Be mindful of the fuel lines and other connections to avoid damaging them.
8. Remove the fuel tank: Once the straps are removed and all connections are disconnected, you can carefully remove the tank from the vehicle.
Reassembly:
Reassembly is the reverse of removal. Ensure all connections are secure and tight before refilling the tank.
Important Considerations:
* Access: Access to the fuel tank may vary depending on your Camaro's configuration (e.g., coupe, convertible). You may need to remove other components to gain access.
* Tools: You will likely need various tools, including wrenches, sockets, screwdrivers, fuel line disconnect tools, and possibly a jack and jack stands.
* Fuel spillage: Be prepared for some fuel spillage. Use absorbent material to soak it up and dispose of it properly.
Again, this is a simplified overview. Use a repair manual specific to your 1990 Camaro for detailed, step-by-step instructions and diagrams. If you're not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic. Improper handling of fuel is dangerous.
