Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery cable to prevent electrical hazards.

2. Relieve Fuel System Pressure

Remove the fuel pump relay from the fuse box.
Start the engine and allow it to run until it stalls to relieve fuel system pressure.
Turn off the ignition and disconnect the negative battery cable again.

3. Remove Affected Fuel Line

Locate the leaking fuel line and carefully loosen the clamps using a socket set.
Gently pull apart the fuel line from the fittings, being cautious of any residual fuel.
If necessary, use a line wrench to avoid damaging the fitting.

4. Install New Fuel Line

Measure and cut the new fuel line to the required length, ensuring it matches the old line.
Push the new fuel line onto the fittings and secure it with clamps, tightening them to the manufacturer's specified torque (usually around 10-15 in-lbs).
Ensure the connections are snug and free of any leaks.

5. Reconnect Fuel System

Reinstall the fuel pump relay.
Reconnect the negative battery cable.
Start the engine and let it run for a few minutes while monitoring for leaks.
