In-tank fuel pump module
A fuel pump module is integrated in the fuel tank.
A fuel sender is installed to the side of the pump module.
A pressure regulator at the fuel pump outlet controls pressure to the fuel line.
Remaining fuel returns to the bottom of the fuel pump, and then re-enters 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.
