Oil by-pass question.

611 1
The port on the top of the stock in-line oil filter housing which is also the pick-up/input source used for a after market by-pass filter. Is that on the output side of the stock filter, meaning the oil is filtered by the stock filter before going to the by-pass filter? I assume it is, but don't know. - I assume y'all know what happens when we assume?
