Here's a general overview. Specific steps may vary slightly depending on your truck's configuration (engine size, cab style, etc.). Consult a repair manual specific to your 2000 Silverado for detailed instructions and diagrams. A Haynes or Chilton manual is a good investment.
1. Preparation:
* Safety First: Disconnect the negative battery cable. Allow the system to depressurize for a few minutes.
* Gather Tools: You'll need various sockets, wrenches (including a fuel line disconnect tool is highly recommended), screwdrivers, jack stands, jack, possibly a fuel pump removal tool, safety glasses, gloves, and rags.
* Vehicle Preparation: Park on a level surface, engage the parking brake, and chock the wheels. You'll likely need to lower the fuel tank.
2. Accessing the Fuel Pump:
* Lowering the Fuel Tank: This is usually the most labor-intensive part. You'll need to access the tank straps or mounting bolts, often located under the truck bed. You may need to remove parts of the exhaust system for easier access. Support the tank with jack stands as you lower it. Be extremely careful not to damage the fuel lines or tank itself.
* Fuel Line Disconnection: Once the tank is lowered enough, you'll access the fuel pump access panel, usually located on the top of the tank. Carefully disconnect the fuel lines. Use the fuel line disconnect tool to avoid damage. Be prepared for a small amount of fuel spillage. Have rags ready to soak it up. You might also need to disconnect the electrical connector.
3. Fuel Pump Removal and Installation:
* Remove the Access Panel: This often involves removing bolts or clamps.
* Remove the Fuel Pump: This may require a fuel pump removal tool, as some pumps are held in place by a retaining ring or clip.
* Inspect the Fuel Pump: Before installing the new pump, inspect the sending unit (fuel level sensor) and the fuel filter (if it's integrated). Replace these if needed.
* Install the New Fuel Pump: Follow the reverse procedure of removal, ensuring everything is seated correctly. Double-check that all the connections are secure and there are no leaks.
* Install the Access Panel: Secure it properly.
4. Reassembly:
* Raise the Fuel Tank: Carefully raise the fuel tank back into its position.
* Reconnect Fuel Lines and Electrical Connector: Ensure everything is secure and leak-free.
* Reconnect Exhaust (if necessary): Reattach any exhaust components you removed earlier.
* Reconnect Battery: Reconnect the negative battery cable.
5. Testing:
* Check for Leaks: Inspect all fuel lines and connections for any leaks.
* Start the Engine: Start the engine and check for proper fuel pressure and operation.
Important Considerations:
* Fuel Pressure: You may want to check the fuel pressure before and after replacement to ensure the pump is functioning correctly. This usually requires a fuel pressure gauge.
* Fuel Filter: While not always integrated with the pump, changing the fuel filter is a good idea, especially if it's been a while.
* Professional Help: If you're not comfortable performing this task, take your vehicle to a qualified mechanic. Improper installation can lead to serious safety hazards.
This is a simplified overview. Always consult a repair manual specific to your 2000 Chevy Silverado for detailed, step-by-step instructions and safety precautions. Failing to follow proper procedures could result in injury or damage to your vehicle.
