What action should be taken to prevent fuel leakage when towing engine-driven equipment?

The recommended action to prevent fuel leakage when towing engine-driven equipment is to always shut off the fuel. This practice is crucial because it directly addresses the risk of spills or leaks occurring during towing. When the fuel supply is shut off, it minimizes the chance of fuel escaping from the tank or fuel lines due to movement, vibrations, or changes in elevation that can happen while towing.

Limiting speed while driving is helpful in some contexts for safety and stability during towing, but it does not specifically target the prevention of fuel leakage. Keeping the fuel tank half full is not a reliable method to prevent leaks; rather, it is advisable to ensure that the tank is properly managed and shut off. Using electric vehicles for towing eliminates the issue of fuel leakage altogether but isn’t a universally practical solution, as not all towing tasks involve electric vehicles. Therefore, shutting off the fuel is the most effective and practical measure to prevent leaks.
