Engine Oil Pump Intake Pipe for BMW Models F30 F80 with Part Number 11417603574

The working principle of the oil suction pipe of the oil pump is to achieve the oil suction function through the change of internal pressure of the pump body.

When the engine is running, the movement of the connecting rod transmits the oil pressure in the oil pan to the pump chamber through the rocker and CAM, reducing the pressure inside the pump body and creating a negative pressure area. This negative pressure will draw the engine oil from the oil pan into the pump chamber.
