On our way home from the DGR ride yesterday, Tom (son-in-law) had to fill his Triumph Bobber's tank as the ride was long enough to light his warning light. We pulled into a Quik Trip and as he was filling the tank the gas nozzle stuck open and he had the same reaction, pull it out of the tank and then try to figure out how to shut it off. Fortunately, he didn't explode in a ball of flames. He spent some time wiping down his bike with paper towels dipped in windshield washer fluid. We got home without further incident.
