fuel injected vehicles will generally have\na a mechanical bellows type fuel pump.\nb a mechanical impeller type fuel pump.\nc an electric fuel pump mounted on the engine.\nd an electric fuel pump mounted in the fuel tank.
Answer
Brief Explanations:
Fuel - injected vehicles typically use an electric fuel pump located in the fuel tank to supply fuel under pressure to the injectors. This helps in achieving better fuel - delivery control and efficiency. Mechanical fuel pumps like bellows or impeller types are less common in fuel - injected systems, and an electric fuel pump mounted on the engine is not the standard placement.
Answer:
D. an electric fuel pump mounted in the fuel tank
