- Locate the fuel rail and inspect the injectors for signs of leakage.
- If leaking, remove the faulty injector using a socket set and replace it with a new one.

3. Repair or Replace Components

Fuel Pressure Regulator:
- Locate the fuel pressure regulator and check for leaks.
- If a leak is found, remove the old regulator and replace it with a new one. Torque the mounting bolts to the specified value (consult service manual for exact torque specifications).
Fuel Tank Repair:
- If the fuel tank is damaged, it may need to be replaced. Drain the fuel, remove the tank using a jack and socket set, and install a new tank following manufacturer instructions.
