Just for reference this is the hydraulic pump p/n 129800 0548 that supplies the fluid to the operating cylinders.
It is located in the trunk under the plastic covering that the spare wheel fits on to.
There are Max and Min fluid marker lines which are about 2.54 cms/1" apart.
The reservoir in the photo is filled to the Maximum level.
Note: entire system holds 1.25 Liters of fluid

1993 SL pump
