Tools Required: Socket set, wrenches, fuel line disconnect tool
Inspect the fuel lines along their entire length for any cracks or leaks.
If a leak is found, replace the damaged section of the fuel line.
Use fuel line clamps to secure any new sections properly.

3. Check and Replace Fuel Filter (if applicable)

Tools Required: Wrench set, rags, container to catch fuel
Locate the fuel filter (check manual for exact location).
Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and remove it.
Install the new filter, ensuring correct orientation, and reconnect the fuel lines.

4. Inspect and Replace Fuel Injector O-rings (if applicable)

Tools Required: Socket set, pick tool
Remove the engine cover if necessary to access the fuel rail.
Carefully disconnect the electrical connectors from the fuel injectors.
Remove the fuel rail and inspect the O-rings on the injectors for damage.
Replace any damaged O-rings with new ones and reassemble the fuel rail.

5. Verify Fuel Tank Integrity

Tools Required: Fuel tank pressure tester
Inspect the fuel tank for any visible damage or corrosion.
Use a fuel tank pressure tester to check for leaks.
If a leak is detected, consider replacing the fuel tank.

6. Reassemble and Clean Up

Reconnect the battery.
Start the engine and check for leaks around the repaired areas.
Clean any spilled fuel and ensure all tools are removed from the engine bay.
