Question 56Motor Plants - Assistant Engineer

The correct answer is B) filter the fuel. The purpose of piece #38 in the fuel injector illustration MO-0059 is to filter the fuel. Fuel filters are a critical component in fuel injection systems, as they remove contaminants and impurities from the fuel before it reaches the injectors. This helps prevent damage to the sensitive fuel system components and ensures efficient and reliable engine operation. The other options are incorrect because they do not accurately describe the function of piece #38. Adjusting the fuel rack spring tension, maintaining fuel pressure, and relieving excess fuel pressure are different functions typically performed by other components in the fuel injection system.
