Hi, I have noted several things related of the fuel system, first a fuel smell when the traffic is slow, the mpg is higer when I start a travel but reduces over the time also always when I arrive at home the Bars in the fuel indicator are one less at the next day, by example 6 one day and 5 at the next, at first I thougth It was my imagination or something related to the expansion of liquids when hot, to check I decided to take the temperature of the tank when I arrive to home, to my surprise when I opened the cap the fuel was boiling vigorously, I have done some checks and when I drive about 30 Km the tank get enough heat to make the fuel boil, specially if I drive on traffic, I tought it was because of the low speed, but to check I drove on a clear road with the same result: the tank makes the fuel to boil, The local dealer (on Queretaro Mexico) saw this situation and call to the regional dealer (Guadalajara Mexico) but with no positive response (more exacty without response), of course the spyder has some recirculating system to burn the gases, but it only works when the engine is on but if the engine is off the fuel is evaporating to the atmosphere and those gases are higly inflamble or even explosive with the apropiate conditions, and even with the system working the quantity of gases can exceed the recirculating capacity, maybe nobody has noted the problem becase we usually open the tank to refill, but never see inside it, could someone check if their spyder has the same problem?, maybe this is the reason of the poor MPG some users have reported and the gas smell other have noted
