The best way to check for gas fumes after fueling a personal watercraft (PWC) is to visually inspect the fuel tank and surrounding areas for any signs of leaks or spills. Additionally, you can smell around the fuel cap and engine compartment for any gasoline odors. If you detect any fumes, it's essential to ventilate the area and avoid starting the engine until the issue is resolved. Always ensure that the PWC is in a well-ventilated space while performing these checks.
