hi. looking at the part numbers for the 997 oil pump, all are 996 numbers (housing, etc.) except for the pump itself. would it be possible to install a 997 oil pump in a 996? I ask because the 997 unit also has a vacuum pump, which would be nice to have instead of relying on manifold vacuum, vacuum tanks, etc.
second question: could this vacuum pump be used to supply vacuum to the aos?
