Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, wrenches, safety goggles, gloves.
Safety Warnings: Disconnect the battery before beginning work on the fuel system. Work in a well-ventilated area and keep a fire extinguisher nearby.

2. Address Fuel Leaks

Sub-step 1: Identify the source of the leak. If found at a connection, tighten fittings with the appropriate wrench.
Sub-step 2: If a fuel line is damaged, replace it. Remove the damaged section by cutting, then install a new fuel line using appropriate connectors.
Sub-step 3: For leaking fuel injectors, replace the O-rings or the entire fuel injector if necessary.
Sub-step 4: If the fuel tank is cracked, it must be replaced. Drain fuel, detach the tank from mounting points, and remove fuel lines before installation of a new tank.

3. Repair EVAP System

Sub-step 1: If the EVAP system is found to have a leak, replace any damaged hoses or valves.
Sub-step 2: Ensure all connections are tight and secure after replacement.
