When inspecting for fuel leaks and tank integrity, which action should you perform?

• A. Inspect for fuel leaks by listening for hissing sounds from vent lines.
• B. Check for wet areas, fuel stains, secure caps, venting free of blockages, and clear sump drains for water or sediment.
• C. Inspect only the exterior for corrosion and ignore venting.
• D. Open the fuel sump and remove debris with no precautions.

Answer: (B)

When checking fuel leaks and tank integrity, you want a thorough visual and physical check of several key indicators. The best practice is to look for wet areas or fuel stains around the tank, confirm the filler cap is secure, ensure venting lines are free of blockages, and verify that sump drains are clear of water or sediment. This combination helps you detect active leaks and ensures the venting and drainage systems will work properly, which are both essential for maintaining tank integrity and preventing leaks. Listening for hissing sounds from vent lines isn’t reliable, because leaks can be silent or not produce audible clues. Inspecting only the exterior for corrosion and ignoring venting misses important failure modes that can compromise the system. Opening the fuel sump and removing debris without precautions is unsafe and could create ignition hazards or exposure.
