If you determine that entrained air in the fuel oil system is causing a diesel engine to stall, you should first check for __________.

🔍 Key Concepts

• Entrained air in fuel systems and how it gets into the fuel stream • Difference between suction side vs discharge/pressure side leaks in fuel piping • Which parts of the fuel system are most likely to draw air into the fuel when slightly loose

💭 Think About

• Think about where a small leak would be able to pull air in rather than just push fuel out • Consider whether air is more likely to enter on the low-pressure, suction side or on the high-pressure discharge side of pumps • Ask yourself which option best matches a location that would cause intermittent air bubbles and engine stalling without a large visible fuel leak

✅ Before You Answer

• Identify which choices describe components on the suction side of a fuel pump vs the pressure side • Verify which condition would allow air ingress instead of (or before) obvious fuel leakage • Confirm which part, if slightly loose, would most directly affect the booster/transfer fuel pump suction to the engine

Question 1 of 27070

If you determine that entrained air in the fuel oil system is causing a diesel engine to stall, you should first check for __________.

fuel leakage in the injector pump's discharge lines

worn gaskets in the transfer pump discharge lines

partially clogged fuel oil discharge strainers

loose fittings in the booster fuel pump suction piping
