FUEL PUMP ASSEMBLY for TOYOTA VIOS is part of the vehicle’s fuel system. The fuel pump assembly draws fuel from the tank and delivers it to the injectors at a consistently maintained pressure. Low pressure causes fuel starvation, leading to engine shuddering and stalling. High pressure results in excess fuel consumption. Typically, the fuel pump is located inside the fuel tank to reduce noise. The fuel also cools the pump, mitigating fuel starvation during high-speed driving. The fuel pump assembly provides a stable fuel supply to the engine, ensuring quick starts and smooth operation; it’s a crucial component in the vehicle’s system. It’s responsible for drawing fuel from the fuel tank and pumping it to the injectors under high pressure, allowing fuel to enter the engine’s cylinder combustion chamber.

Operating Principle of the Fuel Pump Assembly: When the vehicle ignition is turned on, the central processing unit (ECU) activates the relay to supply power to the fuel pump. The pump draws fuel from the tank, passing it through a one-way valve and fuel filter before reaching the injectors. The fuel pump operates continuously from the moment the engine starts. If the engine stalls, the ECU sends a signal to cut off the fuel pump’s power. Modern vehicles often include an additional safety switch based on vehicle acceleration to reduce the risk of fire in case of an accident. Everything is controlled by the ECU, which precisely calculates the fuel consumption of the engine and adjusts the amount of fuel injected into the combustion chamber for greater fuel efficiency.

The fuel pump assembly operates continuously from engine startup. If the engine stalls, the ECU cuts power to the pump. Newer vehicles incorporate safety switches based on vehicle acceleration to minimize fire risks during accidents. The system is managed by the ECU, accurately calculating fuel consumption and adjusting fuel injection for optimal efficiency.
