Solution

1. Preparation

Gather tools and parts needed for the inspection.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear gloves and safety goggles for protection.

2. Visual Inspection

Sub-steps:
- Begin by inspecting the fuel lines from the fuel tank to the engine. Look for cracks, fraying, or any signs of wear.
- Check all connections, including at the fuel rail and injectors, for tightness and signs of fuel residue.
- Inspect the fuel tank for any visible rust or holes.

3. Pressure Testing

Tools Required: Fuel pressure gauge
Sub-steps:
- Connect the fuel pressure gauge to the test port on the fuel rail.
- Turn the ignition to the ON position (do not start the engine) to prime the fuel pump.
- Check the pressure reading; it should match the manufacturer's specifications (usually around 30-50 PSI for most vehicles).
- If pressure is low, inspect all fuel lines and components for leaks.

4. Checking for Injector Leaks

Tools Required: Rags, flashlight
Sub-steps:
- Start the engine and allow it to idle.
- Carefully inspect each fuel injector for signs of fuel leaking around the base.
- Use a flashlight to look for any drips or pooling fuel around the injectors.

5. Final Inspection

Sub-steps:
- If any leaks are found during the visual inspection or pressure testing, mark the locations for repair.
- Clean up any fuel spills with appropriate absorbent materials, disposing of them according to local regulations.
