Overall view of lines for full flow system. Engine out of car in this picture. Here's how to plumb a full flow filter while retaining the mechanical tach (for those with electric tachs, there are other options). What is described and shown here only works for late "A" , "B" and "C" cases. Earlier cases would have to be tapped at a different point for the oil to filter because of different internal plumbing of the 3rd piece. Placement of the oil filter is mostly a personal choice. I have seen them out in the wheel well and on the shroud.
No matter where it goes it will need one line to pass through the ductwork somewhere. I personally favor putting it in the engine compartment off to the left in the rear corner on a bracket. High enough to be able to remove it in an upright position so one can fill it with oil before replacing it and so as not to spill more than necessary when removing.
I also favor using the filter that is compatible with the VW Rabbit/Golf diesel as it is a heavy duty filter with very low pressure drop. Better than the Fram HP1 racing filter.
