1. Remove any protective covers to access the fuel lines.
2. Use a wrench to disconnect the fuel line from the fuel rail or tank.
3. Inspect the lines for cracks, corrosion, or wear; replace any damaged sections.
4. Reconnect the fuel line securely, ensuring no cross-threading occurs.

3. Replace Fuel Injectors (if necessary)

Tools Required: Socket set, torque wrench, injector puller
Sub-steps:
1. Remove the engine cover (if applicable) for access to injectors.
2. Disconnect the electrical connectors and fuel lines from the injectors.
3. Remove the old injectors using an injector puller.
4. Lubricate the O-rings of the new injectors and install them in place.
5. Reconnect the fuel lines and electrical connectors, ensuring a snug fit.

4. Test and Replace Fuel Cap

Tools Required: None (if only the cap needs replacement)
Sub-steps:
1. Inspect the fuel cap for cracks or damage.
2. If damaged, replace it with a new OEM fuel cap.
3. Ensure the new cap clicks securely into place when closing.

5. Reconnect Battery and Perform Final Checks

Reconnect the battery terminals.
Start the engine and visually inspect for any signs of fuel leaks.
Monitor the area for any unusual smells or pressure readings.
