Engine oil lubricating the IP is not true for OM 621 and at least some 615
engines. Does anyone know where the cutoff was between the fuel lubricated
pumps and crankcase oil lubricated pumps? I think it was mid 70s somewhere.
My 66 engines are fuel lubricated. My 81 240D is engine lubed.

Other than the delivery valve o-rings, I'm not aware of any rubber
seals that come into direct contact with the fuel in an inline MB
injection pump. They use engine oil for lubricating the pump
internals.
