Ok, I need more info. 2 part numbers are just not enough!
Are these replacement kits or add-ons to the stock fuel filter?
Are these for 12valves, 24v second gens, 3rd gen only, all of the above, etc?
What are their advantages over the stock fuel filter?
What is their primary purpose? Is there some concern that the bio-D is dirty, or that the crystalization from reaching the cloud point is to be filtered out?
