The fuel pump is located inside a plastic reservoir that is clamped between the top and bottom of the fuel tank and located centrally by protrusions in the bottom of the tank and at the top by the pump cover. The pump is mounted in the tank by screwing the pump cover into a screw ring on the outside of the tank. Movement in the tank is taken up by the fuel pump spring element.
An ejector is "driven" by the flow of fuel from the delivery line via a T-piece. The pump is an electric turbine pump. The ejector is used to ensure the that the pump is supplied with fuel. The location of the pump in the reservoir guarantees the fuel supply when cornering and accelerating even when there is only a small amount of fuel left in the tank.
The reservoir is designed so that a sufficient fuel level is guaranteed in the fuel pump.
A non-return valve on the pump delivery side prevents the pressure in the fuel line dropping as soon as the engine is turned off. The non-return valve on the pump return side prevents the fuel returning the wrong way in case the car should roll over.
The fuel level sensor in the tank is mounted on the fuel pump reservoir via a jointed arm.
