Here's a general outline. Always consult a repair manual specific to your 2002 Tahoe for detailed instructions and torque specifications. Improper procedures can lead to damage or injury.
Safety First:
* Disconnect the negative battery terminal. This is crucial to prevent sparks.
* Ventilate the area extremely well. Gasoline fumes are explosive.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Use jack stands, never rely solely on a jack.
* Consider using a fuel-safe container to catch any remaining fuel.
Steps (General Outline – Refer to your repair manual for specifics):
1. Prepare the Vehicle: Raise the vehicle securely using jack stands. Properly support the frame.
2. Disconnect Fuel Lines:
* Loosen the fuel filler neck: This may require removing components under the rear of the vehicle.
* Locate and disconnect the fuel lines: Carefully relieve the pressure in the fuel lines (consult your repair manual for the proper procedure – this often involves opening a valve to let fuel flow slowly). Use fuel line clamps and appropriate tools to disconnect them. Mark the lines if necessary to ensure proper reconnection.
* Disconnect the fuel pump electrical connector.
3. Disconnect Other Components:
* Disconnect the fuel tank vent line.
* Disconnect the fuel tank straps/supports. These usually involve bolts.
* Disconnect the fuel level sender.
4. Lower the Tank:
* Carefully lower the fuel tank. This might require maneuvering it around the exhaust system and other components. It may be helpful to have an assistant. Do not force it.
5. Remove the Tank: Once clear of all obstructions, carefully remove the tank from the vehicle.
Reinstallation:
Reinstallation is the reverse of removal. Ensure all connections are secure and leak-free. Pay close attention to the fuel lines to prevent leaks. Check for leaks after reinstalling.
Important Considerations:
* Fuel Pump: You may need to access and possibly remove the fuel pump to lower the tank. Refer to your repair manual for the specific details.
* Fuel Tank Straps: These can be difficult to remove and reinstall.
* Exhaust System Interference: The exhaust system might interfere with tank removal. You may need to loosen or remove parts of the exhaust to get enough clearance.
Disclaimer: This is a simplified overview. Attempting this without a detailed repair manual for your specific 2002 Tahoe is highly discouraged. Improper procedures can lead to damage to your vehicle, injury, or fire. If you are not comfortable performing this task, consult a qualified mechanic.
