There are covers on the side and bottom of the pump, the feed pump has a gasket and there is a plate in the rear. All these have gaskets or o-rings that can be purchased through MB.

The big o-ring where the pump seals to the motor also leaks oil and is available. It is difficult if not impossible to pinpoint some of these leaks. I might recommend using one of the florescent dye additives to the oil, drive it, then remove the pump and view the area with the black light. If still inconclusive then relace all the seals; the most expensive was $6.75.
