How should a flexible fuel hose be grounded?

• A. Grounding is not required for flexible hoses.
• B. It must be connected to a grounding wire, and the wire should not be clamped because clamping can cause leakage.
• C. It should be grounded by clamping the wire tightly to the hose fitting.
• D. Grounding should connect directly to hull metal.

Answer: (B)

Grounding a fuel hose is essential to prevent static electricity from building up and potentially igniting fuel vapors during fueling. The hose must be connected to a grounding wire that leads to a proper ground, such as the hull bonding point or the dock’s grounding system, so any static charge can be safely discharged away from the fuel system. The key is to establish a solid electrical connection without clamping in a way that could damage the hose or create leaks—so avoid clamping directly onto the hose fitting. Instead, attach the grounding conductor to a suitable grounding point that provides a reliable, leak-free path to ground.
