U mentioned that your car CURRENTLY has the PI pump installed???? IF so then it does NOT have the vacuum pump either!!!!

Do the wipers stop working when u climb a long hill or under hard acceleration???? IF so then u are already operating withOUT a vacuum pump anyway.

The vacuum wipers operate from 2WO DIFFERETN SOURCES of vacuum. The vacuum pump on the oil pump is is ony an AUXILARY pump for when engine looses vacuum under heavy load.
