Here's a general overview of the steps. Remember, this is not a substitute for a proper repair manual. Variations exist depending on the specific engine and fuel system configuration.
Safety First:
* Disconnect the negative battery terminal. This is crucial to prevent sparks.
* Work in a well-ventilated area. Fuel fumes are highly flammable and dangerous.
* Use proper safety glasses and gloves.
* Have a fire extinguisher nearby.
Tools You'll Likely Need:
* Socket set (metric)
* Ratchet and extensions
* Torque wrench
* Fuel line disconnect tools
* Pry bar (plastic or metal, depending on clips)
* Wire cutters/crimpers (possibly)
* Safety glasses and gloves
* Shop rags
* Fuel pump pliers (optional, but helpful)
* Drain pan
* New fuel pump (ensure it's the correct one for your vehicle)
* Possibly a fuel pressure gauge
General Steps (This is NOT a comprehensive guide):
1. Lower the Fuel Tank: This is usually the most challenging part. You'll likely need to:
* Access the fuel tank straps from underneath the vehicle.
* Carefully loosen and remove the straps (often require socket wrenches).
* Carefully lower the fuel tank. You may need a jack and jack stands for support. Be extremely careful; the tank is heavy and contains fuel. You may need to disconnect the fuel filler neck.
2. Disconnect Fuel Lines:
* Use caution: Fuel will likely remain in the lines. Have rags ready to absorb spills.
* Use the appropriate disconnect tools to separate the fuel lines from the fuel pump. These are often quick-connect fittings.
3. Disconnect Electrical Connectors:
* Unplug the electrical connector from the fuel pump.
4. Remove the Fuel Pump Assembly:
* The fuel pump is usually housed within a retaining ring or cover on top of the fuel tank. You may need to remove this assembly. This step often involves removing bolts or using a specialized fuel pump tool.
5. Replace the Fuel Pump:
* Install the new fuel pump into the assembly, ensuring a proper seal. Sometimes a gasket is involved.
6. Reassemble:
* Reverse the steps to reassemble the fuel pump assembly, fuel lines, and electrical connectors. Ensure all connections are secure.
7. Raise the Fuel Tank: Carefully raise the fuel tank back into position and secure it with the straps.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Prime the Fuel System: You might need to cycle the ignition key a few times (without starting the engine) to prime the fuel pump. Consult your repair manual.
10. Test: Start the engine and check for leaks.
Important Considerations:
* Fuel Pressure: Before starting the process, you might want to release fuel pressure. Your repair manual will guide you on how to do this safely.
* Fuel Tank Straps: The straps can be difficult to access and may require specialized tools.
* Correct Part: Order the correct fuel pump for your specific vehicle. Incorrect fuel pumps can damage the system.
This is a simplified overview. Refer to a repair manual specific to your 2001 Jeep Grand Cherokee Laredo for detailed instructions, diagrams, torque specifications, and safety precautions. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Working with fuel is dangerous and improper repair can lead to serious injury or fire.
