What should be looked for during inspection of an engine-driven fuel pump?

• A. Leaks
• B. Security of mounting
• C. Maximum rated pressure
• D. Leaks and security of mounting

Answer: (D)

Inspecting an engine-driven fuel pump focuses on two safety-critical checks: leaks and how securely the pump is mounted. Visible leaks around the pump or its fittings signal compromised seals or connections, which can lead to fuel loss, fire risk, and reduced fuel delivery. At the same time, the mounting must be secure—bolts or clamps tight and the pump firmly attached without looseness or wobble. A loose mount can cause vibration, misalignment with the drive, accelerated wear, or even failure and additional leaks. While the pump’s maximum rated pressure is important for overall system design, a routine inspection centers on physical condition and proper installation rather than actively testing pressure capability. So looking for both leaks and secure mounting covers the essential checks.
