Tools You'll Need:
* Socket set (metric): Various sizes, including those for the fuel lines and possibly the fuel pump retaining ring.
* Wrench set (metric): For various bolts and fittings.
* Screwdrivers (Phillips and flathead): May be needed for various access panels or components.
* Fuel pump pliers (or a fuel line disconnect tool): To safely disconnect the fuel lines. Never use a standard pliers on these lines.
* Fuel pump removal tool (optional but recommended): Makes removing the fuel pump from the tank much easier.
* Jack and jack stands: Essential for safe working conditions.
* Safety glasses: Protect your eyes from fuel spray or debris.
* Gloves: To protect your hands.
* Shop rags or absorbent towels: To clean up any spilled fuel.
* New fuel pump assembly: Ensure you get the correct one for your specific vehicle.
* Fuel line clamps (if needed): May need replacing.
* Torque wrench: To tighten bolts to the correct specifications. This is crucial for fuel system components.
Steps:
1. Safety First: Disconnect the negative battery terminal.
2. Lower the Fuel Tank:
* Consult your repair manual for the specific location of the fuel tank access panel. It's often underneath the truck bed.
* Support the tank safely using a jack and jack stands. Never work under a vehicle supported only by a jack.
* You may need to remove the skid plate or other components for access to the tank's straps and fuel lines.
3. Disconnect Fuel Lines and Electrical Connector:
* Carefully disconnect the fuel lines using the appropriate fuel line disconnect tool. There will be pressure in the lines, so be prepared for some fuel spillage. Have rags ready.
* Disconnect the electrical connector to the fuel pump.
4. Remove the Fuel Pump Assembly:
* Depending on the year and model, there may be a retaining ring or other fasteners securing the fuel pump assembly to the tank.
* A fuel pump removal tool will significantly simplify this step. Using the wrong tool could damage the tank.
5. Install the New Fuel Pump Assembly:
* Reverse the removal process to install the new fuel pump assembly. Ensure a proper seal.
* Reconnect the electrical connector and fuel lines, ensuring a secure connection.
6. Raise the Fuel Tank: Carefully raise the fuel tank back into its position.
7. Reconnect and Test: Reconnect the battery, then turn the ignition key to "ON" (don't start the engine) to allow the fuel pump to prime. Listen for the pump to run.
8. Start the Engine: Start the engine and check for leaks around the fuel lines and connections. Let the engine run for a few minutes to ensure proper operation.
Important Notes:
* Consult a repair manual: A factory service manual specific to your 2000 Silverado is highly recommended. It will provide detailed diagrams, torque specifications, and step-by-step instructions specific to your vehicle.
* Fuel is Flammable: Work in a well-ventilated area, away from open flames or sparks.
* Fuel is Hazardous: Wear appropriate safety equipment and handle fuel with care.
* Professional Help: If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improperly installing a fuel pump can lead to serious safety hazards.
This is a general guide. The specific procedures will vary slightly depending on your truck. Always prioritize safety and consult your vehicle's repair manual before starting any repair work.
