If wiring cannot maintain six inches away from fuel lines, what minimum separation must be observed?

• A. At least two inches and avoid running parallel to fuel lines
• B. At least twelve inches
• C. No restriction
• D. Three-quarters of an inch

Answer: (A)

The safety rule here centers on preventing ignition hazards when wiring is routed near fuel lines. If you can’t maintain the ideal six inches, you still must keep a minimum separation of two inches and avoid running the wires parallel to the fuel lines. Keeping distance helps reduce the chance of heat transfer, abrasion, or contact with any leaks along a length of line, and avoiding parallel routing minimizes exposure along a continuous stretch where a leak or heat could affect the entire run. The other options don’t fit because twelve inches is more than required by this compromise, no restriction would be unsafe near fuel lines, and three-quarters of an inch is far below the minimum two-inch standard.
