Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and ensure the engine is off and cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Cap

Tools Required: Wrench set
Check the fuel cap for cracks or damage.
If damaged, replace it with a new OEM fuel cap.
Ensure that the new cap is properly tightened to create a good seal.

3. Repair or Replace Fuel Lines

Tools Required: Socket set, fuel line removal tool
Inspect fuel lines for cracks or wear. If any are found, proceed to:
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Use the fuel line removal tool to disconnect the damaged lines.
- Replace with new fuel lines, ensuring proper routing and secure connections.

4. Check and Replace Fuel Injectors (if necessary)

Tools Required: Socket set, fuel injector puller (if needed)
If the injector is leaking:
- Remove the fuel rail by disconnecting it from the intake and unscrewing the mounting bolts.
- Carefully pull out the faulty fuel injector.
- Replace with a new injector, lubricating the O-rings with clean engine oil before installation.
- Reassemble the fuel rail and reconnect it.

5. Test Fuel System

Tools Required: Fuel pressure gauge
Reconnect the battery and install the fuel pump fuse.
Turn the ignition to the "ON" position without starting the engine to pressurize the system.
Connect the fuel pressure gauge to the test port and check for proper fuel pressure.
Look for any signs of leaks during the pressure test.
