Question 1 of 27070

Air is normally bled from a diesel engine fuel system by __________.

🔍 Key Concepts

• Diesel fuel system bleeding procedures • Role of injectors and high‑pressure lines in removing trapped air • Why air in a fuel system affects engine starting and operation

💭 Think About

• Which component of the fuel system is at the highest point where air will collect and can be released safely? • Which action directly opens the path for air to escape from the high‑pressure fuel lines rather than just moving fuel around the system? • For each choice, ask: does this specifically release trapped air from the fuel side of the injection system, or does it mainly affect another system like air start or fuel storage?

✅ Before You Answer

• Identify which option directly involves the injectors or high‑pressure fuel lines • Eliminate options that deal only with air start systems, fuel storage, or routine maintenance rather than bleeding air • Confirm that the correct method would normally be done when the engine has been opened or run out of fuel and needs the lines purged of air
