Mercedes® OEM Vacuum Lock Power Supply Pump,Rebuilt, 1986-1995

The vacuum system on earlier Mercedes models controls several functions, including the locking system, engine shutoff (on diesels), and several aspects of the climate control system. Chasing down a vacuum leak in the system is not impossible, but you will need a vacuum tester (our part number 235980). We offer replacement door, tailgate, gas flap, and trunk lock vacuum valves, repair hose and diaphragms, vacuum fittings, check valves, and more to get your system operating correctly.
