Here's a general outline. This is not a complete, step-by-step guide, and you should consult a repair manual specific to your 2001 Montero (either a Haynes or Chilton manual, or a factory service manual) for detailed instructions and diagrams. Those manuals will show exactly where the line is routed and what components need to be disconnected or removed.
Safety First:
* Disconnect the negative battery terminal before starting any work.
* Work in a well-ventilated area. Fuel fumes are highly flammable.
* Use proper safety glasses and gloves.
* Have a fire extinguisher readily available.
* Collect rags to soak up any spilled fuel.
General Steps (Consult your repair manual for specifics):
1. Identify the Specific Line: Determine precisely which metal fuel line needs replacement. There might be multiple lines near the rear of the engine. Your repair manual will show you exactly which one.
2. Access the Line: This often involves removing other components for better access. This could include:
* Parts of the exhaust system.
* Heat shields.
* Possibly other fuel lines or components. Be extremely careful not to damage any other lines.
3. Disconnect the Fuel Line:
* Relief Fuel Pressure: You'll likely need to relieve fuel pressure in the system. Your repair manual will tell you how to do this safely. This usually involves disconnecting the fuel pump relay. Then, start the engine and let it run until it stalls, indicating pressure is released.
* Disconnect Fittings: Carefully disconnect the fuel line from the fittings at both ends. These fittings might be clamped or use a special fitting type. Use the appropriate wrenches to avoid damaging the fittings. Have rags ready to catch any fuel spillage.
4. Remove the Old Line: Once disconnected, carefully remove the old metal fuel line. Note its routing and any clamps or brackets used to secure it. Take pictures if helpful.
5. Install the New Line:
* Ensure proper fitment: Make sure the new fuel line is the correct replacement part for your vehicle.
* Routing: Carefully route the new fuel line, matching the routing of the old one.
* Secure with Clamps: Use the appropriate clamps to secure the new line in place.
* Connect Fittings: Carefully reconnect the fuel line fittings, ensuring they are properly tightened to prevent leaks.
6. Reconnect Components: Reinstall any components removed for access.
7. Check for Leaks: After reconnecting everything, carefully inspect all connections for leaks. Start the engine and let it run for a while to check for leaks.
8. Reconnect Battery Terminal: Reconnect the negative battery terminal.
Important Considerations:
* Fuel Line Clamps: You'll need the right type of clamps for your fuel lines. These are often spring-type clamps or specific fuel line clamps.
* Specialized Tools: You might need specialized tools to remove or install certain fittings on the fuel lines.
* Professional Help: If you're not comfortable working on your vehicle's fuel system, it's best to take it to a qualified mechanic. This is a job where mistakes can have serious consequences.
Remember, this is a simplified overview. Always consult a repair manual specific to your 2001 Mitsubishi Montero for detailed, step-by-step instructions and diagrams. Safety should be your top priority throughout this process.
