🔍 Key Concepts

• fuel system operation and how fuel is supposed to reach the injectors • what happens to pressure and flow in the fuel system if air gets in • the effect of interrupted fuel supply on engine combustion

💭 Think About

• Think about what an engine needs continuously in order to keep running, and what happens if that supply is briefly broken or becomes inconsistent. • Which of these options is a direct and immediate result of air mixing with fuel in the lines, rather than a long-term mechanical damage or a change in exhaust color? • Consider what a technician usually has to do after changing fuel filters or running a tank dry—what problem are they removing from the fuel lines?

✅ Before You Answer

• Which option describes a problem that would occur right away when air enters the fuel lines? • Eliminate choices that are more related to lubrication problems or overheating from friction rather than fuel delivery. • Ask yourself: which outcome is commonly fixed by bleeding the fuel system to remove air?
