Here's a general overview of the process. Remember, this is NOT a substitute for a proper repair manual. Improperly performing this task can be dangerous due to working with fuel.
Safety First:
* Disconnect the negative battery terminal before starting any work. This prevents accidental sparks.
* Work in a well-ventilated area to avoid fuel fumes.
* Wear safety glasses to protect your eyes.
* Have a fire extinguisher readily available.
* Use appropriate jack stands if working under the vehicle. Never rely solely on a jack.
* Dispose of fuel properly.
General Steps (Consult your repair manual for specifics):
1. Locate the fuel pump: It's usually located inside the fuel tank. Your repair manual will show its exact location.
2. Lower the fuel tank: This usually involves disconnecting the fuel lines, electrical connector, and possibly the fuel tank straps. You'll likely need to support the tank as you lower it. Be extremely careful not to damage the fuel lines.
3. Access the fuel pump: Once the tank is lowered (or partially lowered, depending on design), you'll need to access the fuel pump assembly. This usually involves removing a retaining ring or cover.
4. Disconnect the electrical connector and fuel lines: Carefully disconnect the fuel pump electrical connector and the fuel lines. You might need special tools to disconnect the fuel lines safely and prevent leaks. Have rags ready to absorb any spilled fuel.
5. Remove the fuel pump assembly: This is usually held in place by a retaining ring or clamp. Remove it carefully.
6. Install the new fuel pump: Ensure the new pump is identical to the old one. Install it in reverse order of removal, making sure everything is seated properly.
7. Reconnect the fuel lines and electrical connector: Make sure all connections are tight and secure. Double-check for leaks.
8. Raise the fuel tank: Carefully raise the fuel tank back into its position.
9. Reconnect the fuel tank straps and lines: Secure the tank and ensure all connections are tight.
10. Reconnect the negative battery terminal.
11. Prime the fuel system: You may need to cycle the ignition key a few times (without starting the engine) to prime the fuel system. Consult your repair manual for the proper priming procedure.
12. Start the engine and check for leaks: Listen for unusual noises and check for fuel leaks around the fuel pump and lines.
Tools You'll Likely Need:
* Jack and jack stands
* Socket wrench set
* Wrenches
* Screwdrivers
* Fuel line disconnect tools
* Safety glasses
* Gloves
* Rags
* Fuel pump installation tool (may be required)
* Shop manual specific to your 2000 Chevy S10
Important Considerations:
* Fuel pressure: The fuel system operates under pressure. Failure to properly relieve pressure can lead to injury. Your repair manual will detail this process.
* Fuel type: Ensure the new fuel pump is compatible with your vehicle's fuel type (regular unleaded, etc.).
This is a complex procedure. If you are not comfortable with automotive repair, it's best to take your vehicle to a qualified mechanic. Attempting this repair without the proper knowledge and tools could lead to damage to your vehicle or personal injury.
