Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before beginning the procedure.

2. Inspect and Replace Fuel Lines

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect the fuel lines for signs of wear or leaks.
- If damaged, use a socket set to disconnect the fuel lines from the fuel tank and engine.
- Replace with new fuel lines, ensuring proper routing and securing with clamps.
- Torque connections to manufacturer specifications.

3. Inspect and Replace Fuel Cap

Sub-steps:
- Remove the existing fuel cap by turning it counterclockwise.
- Inspect the rubber seal for cracks or wear.
- Replace with a new fuel cap if damaged or if it fails to seal properly.

4. Inspect and Replace Fuel Injectors (if necessary)

Sub-steps:
- Remove the intake manifold (if required) to access the fuel injectors.
- Disconnect the electrical connectors from each fuel injector.
- Use a fuel line disconnect tool to carefully remove the fuel rail and injectors.
- Inspect and replace any faulty injectors with new ones.
- Reinstall the fuel rail and reconnect all electrical connectors.

5. Test Fuel System Pressure

Sub-steps:
- Connect a fuel pressure gauge to the Schrader valve on the fuel rail.
- Turn the ignition key to the "On" position to pressurize the system without starting the engine.
- Check the pressure reading against manufacturer specifications; replace the fuel pump if pressure is low.
