Question 205Motor Plants - 1st Asst/Chief

The correct answer is B) serious fire hazard. A leak in the high-pressure fuel piping between the injection pump and fuel nozzle poses a serious fire hazard. This is because the fuel in this section of the system is under very high pressure, typically several thousand pounds per square inch. A leak in this high-pressure system can result in fuel being sprayed out under immense force, which greatly increases the risk of ignition and a resulting fire. This fire hazard is the primary reason an immediate repair is required if such a leak occurs, as it poses a significant safety risk. The other answer choices, while potentially valid concerns, are not the primary reason for the urgency of the repair in this situation.
