Which feature is associated with fuel contamination control?

• A. Sump and drains collect water and sediment
• B. Pressure gauges circulate fuel
• C. Temperature sensors heat fuel
• D. Vent lines measure contamination

Answer: (A)

Contamination control in fuel systems relies on removing water and sediment before the fuel reaches the engine. Sumps located at low points in the tanks collect any free water and sediment that settle out of the fuel. Drains allow you to periodically drain these liquids and inspect what’s in the sump, giving a direct way to monitor and remove contamination. That’s why this feature—sump drains collecting water and sediment—is the best association. The other options describe components that monitor pressure, heat fuel, or vent vapors, rather than directly removing or identifying water/sediment contamination in the fuel.
