A fuel pump is integrated in the fuel tank, which is the same type system used in automobiles.
A fuel sender is installed to the side of the pump module.
A pressure regulator at the fuel pump outlet control pressure to the fuel line.
Remaining fuel returns to the bottom of the fuel pump, and then reenter the fuel pump inlet nearby.
With the suction generated at this time, fuel in the fuel tank is fed into the fuel pump module. As a
result, fuel is supplied to the fuel pump inlet without interruption for reliable fuel pressure.
