Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.

• Sub-step 1: If a fuel line is damaged, cut the affected section out and replace it with a new section of high-pressure fuel line.
• Sub-step 2: If the fuel tank has a crack, remove it from the vehicle, clean the area around the crack, and apply a fuel tank repair kit or replace the tank entirely if the damage is severe.
• Sub-step 3: If fuel injectors are leaking, remove the faulty injector using a socket set and replace it with a new injector.

4. Reassemble and Test

• Sub-step 1: Reconnect any removed components, ensuring all connections are secure.
