Oil Filter Housing Question

[Hey_You]

Which part of the oil filter is filtered. The center sections, or the outsides? I'm wondering because I need to know which port to tap into for some filtered oil at the housing.

dirty oil goes in along the outside and filtered oil comes out the center

[Hey_You]

Thanks a ton, you actually just REALLY helped me out. Now I know where I need to drill and tap ;)
