The electric motor actually works in the fuel in the oil pump casing. Don't worry, because there is nothing in the casing that can be ignited. The fuel can lubricate and cool the fuel motor. The oil outlet A check valve is installed at the pump, and a pressure limiter is located on the pressure side of the oil pump housing with a passage to the oil inlet
How the fuel pump works When the rotor disc rotates, the roller is pressed outward by centrifugal force, like a rotating oil seal, the rotor rotates, the pump works, sucks fuel from the oil inlet, and presses the fuel from the oil outlet into the fuel system, when the oil pump is turned off , the check valve at the oil outlet is closed to prevent the fuel from flowing back to the fuel tank through the fuel pump, and the fuel line pressure maintained by the check valve is called "residual pressureProduct Parameter
