Which statement about replacing fuel pumps is accurate?

• A. The new pump must be installed deeper in the tank
• B. It must have a higher pressure rating
• C. It must have the same pressure rating as the original
• D. Any pump will suffice as long as it fits

Answer: (C)

The statement about replacing fuel pumps that is accurate is that the new pump must have the same pressure rating as the original. This is crucial because the fuel pump is designed to deliver fuel at a specific pressure to ensure optimal engine performance and efficiency. If the replacement pump has a different pressure rating, it can lead to insufficient fuel delivery or excessive pressure, both of which can cause poor engine performance, misfires, or even damage to the fuel delivery system and engine components. Using a pump with the same pressure rating as the original ensures compatibility with the vehicle's fuel system, maintains proper fuel flow, and supports the appropriate air-fuel mixture for combustion, which is vital for maintaining engine efficiency and emissions standards. Thus, selecting a fuel pump with the correct specifications, especially the pressure rating, is important for the vehicle's overall operation and longevity.
