In a fuel system, what is the function of bonding wire and ground?

• A. Fuel Filter
• B. Fuel Tank
• C. Bonding Wire and Ground
• D. Carburetor

Answer: (C)

Bonding wire and ground prevent static electricity from building up in a fuel system by tying all conductive parts together and providing a path to earth. As fuel flows, friction and movement can generate static charges on metal surfaces. If those charges aren’t equalized, a discharge can occur when fueling equipment is connected or disconnected, potentially igniting fuel vapors. The bonding wire links metal components such as the fuel tank, fuel lines, fittings, and dispensing equipment, while grounding gives a direct path to the earth. This keeps everything at the same electrical potential and safely dissipates any charge. The other components mentioned have different mechanical or filtration roles and don’t specifically address static discharge safety.
