As an update to the fuel filter articles, here is DanG144's .pdf file on what's inside the housing center and how fuel is routed inside it. This only applies to the 2 hole wide mouth filter housing because the 1 hole narrow mouth housing is built completely differently.

The article was split into 2005-2006:http://www.myturbodiesel.com/1000q/a5/fuel-filter-VW-Jetta-TDI-2005-2006.htm and 2009-2010: http://www.myturbodiesel.com/1000q/a5/2009-2010-VW-TDI-fuel-filter.htmsince the procedures are slightly different but you can view the .pdf file in either.

Here's a direct link to the file. https://www.myturbodiesel.com/d2/images/pdf/Fuel_Filter_housing_construction_and_flow_paths.pdf
