For Mercedes-Benz W221, multiple starts required, acceleration stutter, or power drop at high speed indicates aging factory fuel pump assembly and insufficient fuel pressure. The part supplies fuel from the tank to the engine, maintaining low-pressure fuel system pressure for smooth operation. Fits W221/S350, CL550, S550; OEM 1714700990. Installation requires disconnecting the battery negative and inspecting the pump seal for integrity to avoid leaks or noise after installation.
