Hi Dennis, I'm not sure this is a good comparison. Modern manufacturers are no longer building vehicles with a 20-year lifespan in mind, VW included. Modern fuel systems are putting the pump in the tank and using the computer to control fuel pressure so there is no need for a return line. But a GMC Savanna fuel pump assembly costs $700 from the dealer. In 2003 my 2001 Ford Focus had a recall on the "pump-in-tank" the week after it left me stranded. Maintenance is the key to prolonging the life of a 20-something year old vehicle. Change the filter at the recommended interval (6 months) and you won't have a problem. Changing fuel lines on a regular basis is also a good idea. (5-6 year interval??) I would rather trust a filter I can replace than a screen or sock inside the tank that I can't see, and I'd rather see it in front of the pump. YMMV.
