Ferrari 248 F1 - fuel system 21 October 2006
According to Ferrari, the failure that stopped Michael Schumacher running in the third qualifying session in Brazil was related to the fuel pump. The failure prevented fuel being correctly transferred from the tank to the engine's injection system. A Formula One car's fuel system can be summarised in four main elements: the pump (1) aspirates the fuel from the tank by means of a small suction duct (2), which can catch fuel even when the level in the tank is very low. The fuel is then transferred to a central main duct (3). This is connected to a final duct (4), which is in turn linked to the engine's injection system.
