1992 mercedes 190E can't prime the oil pump. Put new housing and oil pump gear and primed it but the pressure hasn't come up yet. any sugestions?
You should try to pack the gears and pump cavity with petroleum jelly which will prime the pump and the oil will then displace the jelly. If you use any other kind of grease, the oil will not be able to displace it so make sure you only use petroleum jelly. This is the stuff used in the medical field but works great for this purpose too. Let me know how it goes and whether you have any further questions. Thanks and good luck

according the the haynes book the pump isn't self priming , the pump has to have oil put in the pump to start the prime sequence. A vacuum pump doen't drive the pump on this model,
the crankshalf does.
