What is one method to prime a fuel injected engine?

• A. A manual priming pump which delivers fuel to the discharge nozzles.
• B. An electric fuel pump delivering fuel to the discharge nozzles.
• C. The excess fuel delivered by the engine driven fuel pump.
• D. Pumping the throttle lever while turning the engine over on the starter motor.

Answer: (B)

One effective method to prime a fuel injected engine involves using an electric fuel pump to deliver fuel to the discharge nozzles. This process is crucial for ensuring that fuel reaches the injectors before the engine starts. When the electric fuel pump is activated, it builds up pressure in the fuel system, allowing fuel to flow through the lines and reach the fuel injectors. This is important because fuel injectors need a certain fuel pressure to atomize the fuel properly for combustion. By priming the system with the electric fuel pump, it ensures that the engine has a sufficient amount of fuel ready to be injected as soon as the starter engages, facilitating an easier and more reliable engine start. While other methods might provide fuel to the engine, using an electric fuel pump is specifically designed for this purpose and offers efficiency and reliability, making it a commonly adopted practice in modern fuel injected engines.
