Link to overhaul kit: https://mercedessource.com/store/1977... This pump is sometimes called the primer pump, but it does more than just "prime." It constantly pulls the fuel from the tank and delivers it under pressure to the engine-driven injection pump. Applies to OM616 and OM617 diesel engines from the mid to late 1970s to the mid-1980s.
