Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working on the fuel system.

2. Inspect and Repair Fuel Lines

Tools Required: Wrench set, screwdriver, fuel line disconnect tool
Carefully remove any protective covers to access the fuel lines.
Use the wrench to disconnect the fuel line fittings at both ends.
Inspect the lines for cracks or signs of wear. Replace any damaged lines with new ones.
Reconnect the fuel lines securely and ensure no leaks are present.

3. Replace Fuel Injector Seals

Tools Required: Socket set, torque wrench, fuel injector seal kit
Remove the intake manifold if needed to access the fuel injectors.
Disconnect the electrical connectors from the fuel injectors.
Carefully pull out the fuel injectors and replace the O-rings with new seals from the kit.
Reinstall the fuel injectors, ensuring they are seated properly and reconnect the electrical connectors.

4. Check Fuel Cap

Inspect the fuel cap for any cracks or damage. If damaged, replace the fuel cap with an OEM part.
Ensure that the fuel cap seals properly when closed.
