The problem
REPEATED TOPPING OFF OF FUEL TANK DURING REFUELING REDUCES THE EXPANSION SPACE WITHIN THE TANK ALLOWING VAPORS TO ESCAPE FROM THE CHARCOAL FILTER TO OUTSIDE RATHER THAN BEING INDUCTED INTO THE ENGINE.
Risk
ESCAPING VAPORS COULD IGNITE BY HEAT EMITTED BY THEEXHAUST SYSTEM.
What owners should do
INSTALL REDESIGNED FILLER NECK AND A NEW VENT VALVE AND HOSE FOR CHARCOAL FILTER. ALSO, STOP REFUELING WHEN PUMP NOZZLE SHUTS OFF.
