Here's a general outline. This is not a comprehensive guide and should not be used as a sole source for instruction. Consult a repair manual specific to your 1998 Jeep Cherokee Limited for detailed instructions, diagrams, torque specifications, and safety precautions. A Haynes or Chilton manual would be a good investment.
Safety First:
* Disconnect the negative battery cable. This is crucial to prevent sparks.
* Ventilate the area. Work in a well-ventilated space, away from any ignition sources.
* Wear safety glasses and gloves. Fuel is irritating to skin and eyes.
* Have a fire extinguisher readily available.
Steps (General Outline):
1. Prepare the vehicle: Jack up the vehicle and secure it safely on jack stands. Locate the fuel pump access panel (usually under the rear seat or in the bed of the truck).
2. Drain the fuel tank: This is crucial to reduce the amount of fuel you're working around. You'll need a fuel siphon pump or a method to drain the tank safely.
3. Remove the access panel: Access to the fuel pump is usually gained by removing the access panel.
4. Disconnect the electrical connector: Carefully disconnect the electrical connector from the fuel pump.
5. Disconnect fuel lines: Carefully disconnect the fuel lines leading to and from the fuel pump. You'll likely need fuel line disconnect tools to avoid damaging the lines. Have rags ready to absorb any spilled fuel.
6. Remove the fuel pump assembly: This usually involves removing retaining bolts or a retaining ring. The assembly will likely include the fuel pump, fuel level sending unit, and possibly other components.
7. Install the new fuel pump assembly: Carefully install the new fuel pump assembly, ensuring it's seated correctly. Pay close attention to the orientation of any components.
8. Reconnect fuel lines: Reconnect the fuel lines securely, ensuring tight connections to prevent leaks.
9. Reconnect the electrical connector: Reconnect the electrical connector to the fuel pump.
10. Reinstall access panel: Reinstall the access panel.
11. Refill the fuel tank: Carefully refill the fuel tank with fresh fuel.
12. Lower the vehicle: Lower the vehicle carefully.
13. Reconnect the negative battery cable: Reconnect the negative battery cable.
14. Prime the fuel system: This may involve cycling the ignition switch a few times (without cranking the engine) to allow the fuel pump to prime the system. Consult your repair manual for the proper priming procedure.
15. Start the engine: Start the engine and check for leaks. Listen for the fuel pump to operate. Check for any fuel leaks around the connections.
Important Considerations:
* Fuel pressure: Your repair manual will outline the proper fuel pressure for your vehicle. You may need a fuel pressure gauge to check the fuel pressure after installation.
* Fuel pump strainer: The fuel pump often has a strainer. This may need to be cleaned or replaced.
* Fuel pump relay: A faulty fuel pump relay can also cause fuel delivery problems. Consider testing the relay before replacing the fuel pump.
Again, this is a simplified overview. Use a repair manual specific to your 1998 Jeep Cherokee Limited for complete and accurate instructions. Failure to follow proper procedures can lead to injury or damage to your vehicle. If you have any doubts, seek professional help.
