Donny, you do NOT! need that in tank fuel pump. I don't know why they put them on the manual transmission cars but not the auto. Just put the filter in it. Some people think it was just because Porsche thought the Mt cars would be driven harder with low fuel. All that in tank pump does is."assist" when fuel is low and you are cornering hard and sucking air occasionally. It just gets fuel to the regular pump a bit faster. The filter is what you really want to help keep the fuel clean.
