摘要： The invention relates to a portable handheld work apparatus having an internal combustion engine and an injection pump. The work apparatus includes an injection-pump block which is mounted on the housing of the work apparatus. The injection-pump block includes a feed pump for pumping fuel from a fuel tank mounted in the housing of the work apparatus and the injection pump for injecting fuel into the engine. An interface is provided between the block and the housing through which connecting lines are passed. Each line includes a connecting receptacle and a plug-in element at the interface. The plug-in elements jointly engage corresponding ones of the connecting receptacles when the injection-pump block is seated in the housing of the work apparatus. In this way, all connections of the connecting lines are made simultaneously when fixing the injection-pump block in position. A simplified installation of the injection-pump block in the housing of the work apparatus is achieved with the invention.
