This seems to work very well(300d 2.5). As you move the pump after positioning the engine to the timing mark slowly twirl the tool by the threaded end while exerting very light pressure on it.When the timing piece in the pump lines up the groove in the tool will engage it.It will not engage even if it is just the slightest bit off.Of course you must first look in the hole and determine which way the pump needs to be moved.Worked for me,easy to make and probably free as everyone has a few extra bolts lying around and a couple of hacksaw blades.
