I look apart a fuel pump to see what is inside and how it works. I made a video on the process:
Here are a few pictures for your information:
Fuel pump is stored inside the gas tank:
Removed from the vehicle, it is an assembly consisting of the sender unit, motor/pump, filter, pressure regulator and empty tank sensor:
A look at how the system works as a hole:
There’s a sock on the bottom that acts as a filter to the motor:
On the bottom is this little valve that controls the pressure by allowing excess fuel to go back to the tank:
A closer look at the printed circuit board where the float picks up the resistance readings for the fuel gauge:
Inside the motor, a paddle with a spiral to force gasoline through the motor itself:
Inside the fuel filter/ pressure regulator assembly:
All the parts that make up the fuel pump assembly:
