- Examine all fuel lines for cracks or loose connections.
- Tighten any loose fittings; replace lines if damaged.
Fuel Injectors:
- Remove the engine cover (if necessary) to access the fuel injectors.
- Inspect for fuel leakage around the injectors; replace any leaking injectors.

3. Repair or Replace Components

Fuel Tank Replacement:
- If the tank is damaged, remove it completely, replace with a new or refurbished tank, and reconnect all fittings securely.
Fuel Lines Replacement:
- If any fuel lines are found to be compromised, replace with OEM-spec lines, ensuring all connections are tight and secure.
Fuel Injector Replacement:
- If injectors are faulty, remove and replace with new injectors, ensuring proper sealing.

4. Reassemble and Reconnect

Reconnect any components removed during inspection and replacement.
Reconnect the battery and ensure no tools are left in the engine bay.
