The fuel system in a 1992 Mercury Grand Marquis consists of several key components: the fuel tank, fuel pump, fuel filter, fuel lines, and fuel injectors. The fuel pump draws gasoline from the tank and sends it through the fuel filter to remove impurities. From there, the clean fuel travels through the fuel lines to the fuel injectors, which atomize the fuel for optimal combustion in the engine. The system operates under pressure to ensure efficient fuel delivery.
