Robert Bosch LLC (Bosch) has submitted a Defect Information Report based upon decisions made by Ford Motor Company and General Motors to conduct recalls (numbers 18V392 and 18V358 respectively) to inspect and replace certain Robert Bosch HDP5 High Pressure Fuel Pump Assemblies, part numbers 0261520518 and 0261520515. Welds between the pump housing and the mounting flange may fracture, possibly causing a fuel leak.
