I've searched the forum but cannot find an answer. Does anyone know how to find out which manufacturers supply OEM parts for a given model and year?

For example, if I wanted to find out the OEM for my vacuum pump, how could I determine this without pulling the pump itself.

Many thanks in advance. This is one of the most useful sites on the net.

One way I do it is look for my year/model in the FastLane, find the part that I want, and usually the parts sold by FastLane are sold under the OEM name...from there, you can get a pretty good sense of who is the OEM manufacturer of the part...but taking a wild guess, it is probably Bosch...
