When inspecting fuel system components, what areas should be checked for integrity?

• A. Tanks, vents, and lines.
• B. Only fuel pump.
• C. Ignition coils.
• D. Catalytic converter.

Answer: (A)

Maintaining fuel system integrity means ensuring every part that stores and transports fuel is free from damage and leaks. The key areas to inspect are the fuel tank, the venting system, and the fuel lines. The tank should be checked for cracks, corrosion, dents, and any signs of leaking or mounting damage. The venting system must be intact so pressure and vapor buildup don’t cause leaks or safety hazards, so inspect vent hoses, fittings, and routing for cracks, blockages, or improper connections. The fuel lines—both supply and return—need to be free of leaks, cracks, abrasion, and loose fittings, with clamps and connections secure and properly routed away from heat sources. While the fuel pump is part of the system, it doesn’t by itself address overall integrity; ignition coils and the catalytic converter belong to ignition and exhaust systems, not the fuel delivery path.
