Solution

1. Preparation

Tools Required: Safety glasses, gloves, fuel pressure gauge, smoke machine, UV light, leak detection dye.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent sparks.

2. Visual Inspection

Sub-steps:
- Check the fuel tank for any physical damage or corrosion.
- Inspect all visible fuel lines for wetness or cracks.
- Examine the fuel injectors for any leaks around the seals.

3. Fuel Pressure Check

Sub-steps:
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the ON position (do not start the engine) to pressurize the system.
- Compare the reading on the gauge to the manufacturer’s specified fuel pressure range.
- If the pressure is low, it may indicate a leak or a faulty fuel pump.

4. Smoke Test

Sub-steps:
- Connect the smoke machine to the fuel filler neck or any other access point in the fuel system.
- Activate the smoke machine and observe for smoke escaping from any leaks.
- Mark any areas where smoke is observed for further inspection.

5. Dye Test

Sub-steps:
- Add the leak detection dye to the fuel tank as per the product instructions.
- Allow the vehicle to run for a short period to circulate the dye.
- Use a UV light to inspect the fuel lines, injectors, and tank for any glowing areas indicating a leak.
