What is the best way to check for fuel vapours after fueling a PWC?

The best way to check for fuel vapors after fueling a personal watercraft (PWC) is to visually inspect the fuel tank and surrounding areas for any signs of leaks or spills. Additionally, closely smell around the fuel cap and vent to detect any odors indicating vapor presence. If any leaks or vapors are suspected, it's crucial to allow the area to ventilate and avoid starting the engine until the situation is confirmed safe. Always follow the manufacturer's guidelines for safety when fueling and checking for leaks.
