THE TRUNK SMELLS LIKE GASOLINE. THE CABIN SMELLS LIKE GASOLINE. WHILE RESEARCHING ONLINE, THERE ARE NUMEROUS COMPLAINTS ABOUT A GAS SMELL ON THESE CARS.
FUEL TANK SHUTS OFF AFTER ONLY 3 TO 4 GALLONS. THEN I HAVE TO SQUEEZE AND PUMP A GALLON AT A TIME UNTIL FULL! I HAVE TRIED SEVERAL GAS STATIONS, SEVERAL PUMPS AND PUMP TYPES, I HAVE VARIED THE FLOW RATIO AND THE PROBLEM PERSISTS. THE LOCAL DEALERSHIP IS VERY HELPFUL AND THE MOST CURTIOUS, BUT THE PROBLEM IS STILL PRESENT AFTER THEY HAVE REPLACED THE CHARCOAL CANNISTER, CHECKED THE LINES AND REPLACED THE GAS TANK (SINCE THE BACK FLOW TRAP IS INSIDE THE TANK. THEY WILL BE TRYING AGAIN TO FIX THIS PROBLEM ON MAY 10TH. THEY HAVE A TECHNICIAN THAT IS HERE FROM JAPAN THAT WILL BE CHECKING IT OUT ALL DAY. THIS APPOINTMENT MAKES 4 SCHEDULED VISITS FOR THE SAME PROBLEM. I LOVE THIS VEHICLE,BUT THE FUEL FILLER PROBLEM IS UNACCEPTABLE. I KNOW THERE WAS A SIMILAR PROBLEM WITH THE 1999 MIATA. ON THE MIATA FORUMS ON THE WEB OTHER 2000 MIATA OWNERS HAVE THIS PROBLEM TOO. THANK YOU, MR.

GAS PUMP SHUTS OFF BEFORE THE TANK IS FILLED! THIS HAPPENS EVERY TIME. THE PUMP SHUTS OFF AFTER 1 TO 3 GALLONS AND THEN I CAN GET ANOTHER 5 TO 8 GALLONS IN THE TANK BY SQUEEZING THE NOZZLE DOZENS OF TIMES! I HAVE TRIED SEVERAL GAS GRADES, STATIONS, FLOW RATES AND NOZZLE STYLES, BUT NOTHING FIXES THIS PROBLEM!*AK
