Here's a general overview. This is not a comprehensive guide and specific steps might vary slightly depending on the year of your S-10. Always consult a repair manual specific to your vehicle's year and model for detailed instructions and diagrams. A Haynes or Chilton manual is a great investment.
Tools You'll Likely Need:
* Socket set and wrenches: Various sizes will be needed.
* Screwdrivers: Phillips and flathead.
* Fuel line disconnect tool: Essential to prevent damage to the fuel lines.
* Jack and jack stands: For safe access to the fuel tank.
* Wheel chocks: To secure the vehicle.
* Safety glasses and gloves: Protect yourself from fuel and sharp edges.
* New fuel pump assembly: Make sure it's the correct part for your vehicle's year and model.
* Fuel pump strainer/sock (if included in the kit or needs replacing): A clogged sock can cause fuel pump failure.
* Wrench or socket for the fuel tank sending unit: Often located in the tank with the fuel pump.
* Shop rags or absorbent cloths: To clean up any spilled fuel.
* Torque wrench: To tighten bolts to the manufacturer's specifications.
General Steps:
1. Safety First: Disconnect the negative battery terminal.
2. Lower the Fuel Tank: This usually involves accessing it from underneath the vehicle. You may need to remove the spare tire and some underbody shields. Consult your repair manual for specific instructions on your S-10. Carefully lower the tank using a jack and jack stands, supporting it securely.
3. Disconnect Fuel Lines: Using the fuel line disconnect tool, carefully disconnect the fuel lines from the fuel pump. Have rags ready to soak up any spilled fuel. Be extremely careful not to damage the lines.
4. Disconnect Electrical Connectors: Disconnect the electrical connectors from the fuel pump.
5. Remove the Fuel Pump Assembly: This usually involves removing a retaining ring or bolts that hold the assembly in the tank. The fuel pump is often part of a larger assembly that includes the fuel level sender.
6. Inspect and Replace the Strainer/Sock: If the strainer/sock is included with the new fuel pump, or if it's visibly dirty or damaged, replace it.
7. Install the New Fuel Pump Assembly: Carefully install the new fuel pump assembly, ensuring it's properly seated and secured.
8. Reconnect Everything: Reconnect the electrical connectors and fuel lines, ensuring tight connections. Double-check that the fuel line clamps are properly secured and leak-free.
9. Raise the Fuel Tank: Carefully raise the fuel tank back into its position.
10. Reconnect Everything Else: Reinstall any underbody shields, the spare tire, etc.
11. Reconnect the Battery: Reconnect the negative battery terminal.
12. Prime the Fuel System: Before starting the engine, you may need to prime the fuel system. This might involve turning the ignition key to the "on" position several times (without cranking the engine) to allow the fuel pump to fill the lines. Your repair manual will detail the correct procedure.
13. Start the Engine: Start the engine and check for leaks. Look for fuel leaks around the fuel lines and the fuel pump area. Listen for unusual noises from the fuel pump.
Important Considerations:
* Fuel Pressure: Some fuel systems require a fuel pressure gauge to verify proper operation after replacement.
* Fuel Tank Removal: Depending on your S-10's year and model, dropping the tank may be the only way to access the fuel pump, or there may be access panels. Your repair manual will have the necessary steps.
This is a simplified overview. Always consult a repair manual specific to your vehicle's year and model before attempting this repair. If you are not comfortable performing this repair yourself, take your S-10 to a qualified mechanic. Working with gasoline is dangerous and mistakes can have serious consequences.
