The low pressure fuel pump build into the fuel tank.
The ECM turns the fuel pump relay ON/OFF and controls the low-pressure fuel pump.
The low pressure fuel pump is integrated with a fuel pressure regulator and a fuel filter.
When the ignition switch is turned ON, the fuel pump operates for 1 second to start the engine. During cranking and while the engine is running, the fuel pump relay turns ON to operate the lowpressure fuel pump, and gasoline inside the fuel tank is sent to the fuel line after passing through the fuel filter. When the fuel pressure in the fuel line reaches or exceeds the specified pressure, the lowpressure fuel regulator opens, and the gasoline in the fuel line returns to the fuel tank, lowering the fuel pressure.

FUEL LEVEL SENSOR
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and transmits a signal to the combination meter. The combination meter sends the fuel level sensor signal to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
