When do you check for gas fumes when refueling a pwc?

You should check for gas fumes when refueling a personal watercraft (PWC) before you start the refueling process, during refueling, and after you finish. Ensure the area is well-ventilated and look for any signs of leaks or strong odors. If you detect gas fumes at any point, stop refueling immediately and address the issue before proceeding. Always follow safety guidelines to prevent fire hazards.
