About Fuel Pump Module Assembly
The assembly of the fuel pump module is mounted in the fuel tank and includes the sending mechanism for electric fuel pump, fuel strainer, and fuel gauge. The module controls the voltage supplied to the fuel pump of a car. The fuel pump driver module, by regulating the voltage, maintains optimum fuel pressure and fuel supply to the engine over its maximum operating range. The fuel-pump driver module controls new, computer-controlled, fuel-injected engines with high-pressure fuel pumps. Consistently, the electric fuel pump provides high pressure petrol. The fuel pump is fitted with an impeller at the end of the motor shaft which draws fuel from one end and pushes it out at the other end of the pump. The fuel gauge sender, also commonly referred to as the fuel sending unit, is the part responsible for sending the signal in the instrument cluster which operates the fuel level gauge. The fuel sending device consists of an arm, float, and a resistor which changes according to the float's location. The sending unit for fuel gauge consists of a float connected to a variable resistor. If the fuel is consumed and the volume in the tank decreases, the float decreases, which in effect increases the current sent from the variable resistor to the gauge, allowing the needle of the fuel gauge to also fall. The fuel tank is running low, a leading cause of fuel pump failure. The fuel in the gas tank heats up much faster by running on a low gas tank which causes the fuel pump to overheat or even worse run dry. One such vehicle will permanently damage the fuel pump until it runs out of fuel. The pump has to work a lot harder to generate the same pressure when the fuel level is low. This is because the decreased weight of fuel will not drive fuel into the pump any more. Other triggers such as rust, dirt, or debris in the gas tank can very quickly damage the fuel pump.
What is the purpose of Fuel Pump Module Assembly?
The assembly of the fuel pump module provides the fuel injection system with pressurised fuel. It also lets you know the fuel inside the tank
How Fuel Pump Module Assembly Works?
The assembly of the fuel pump module is mounted in the fuel tank and includes the sending mechanism for electric fuel pump, fuel strainer, and fuel gauge. Within the fuel tank are mounted electric fuel pumps. Some cars are also likely to have two fuel pumps. The powertrain control module energises a relay which supplies voltage to the fuel pump when the driver turns the ignition key on. The motor inside the pump begins spinning and runs through an inlet tube and mesh filter socket for a few seconds to create pressure in the fuel system Fuel is drawn into the pump. The fuel then exits the pump through a one way test valve and is forced through the fuel line and filter toward the engine. The fuel filter removes any dust, dirt or other solid pollutants that could have passed through the pump to prevent the fuel injectors from being obstructed by such particles. The fuel then flows onto the engine's fuel supply rail and is directed to the individual fuel injectors. On the fuel rail, a fuel pressure regulator retains fuel pressure, and returns excess fuel to the tank. The fuel pump has a fuel gauge transmitting unit assembly that includes a float on the instrument panel that sends an electrical signal to the fuel gauge.
