What is the minimum required distance between a strapped battery and any metallic fuel line?

• A. 6 inches
• B. 12 inches
• C. 18 inches
• D. 24 inches

Answer: (B)

Keeping a source of electrical energy away from a fuel line is about preventing ignition from sparks or heat. A strapped battery can produce arcs or heat during charging and discharging, and a metallic fuel line can carry flammable vapors. Placing them at least twelve inches apart creates a safe buffer so that any spark or heat is unlikely to reach the line and ignite vapors. This twelve-inch minimum is the standard you’re aiming for; more distance adds extra safety but isn’t required by the minimum rule.
