The Mercedes-Benz W654 1.6 and 2.0L diesel engines use a timing chain driven high pressure diesel fuel pump. The timing chain is mounted at the back of the engine which means any task involving its removal will require the engine to be removed unless the pump sprocket can be held in place while the pump is extracted. The Laser 8095 allows the user to lock the pump sprocket securely in place while removing and refitting the HP fuel pump.
