Do VW tanks have a little metal filter "sock" inside the tank, on the pick-up
tube? I can't recall what vehicle I have worked on that had this little
permanent sock, but the idea was to catch major chunks of crud prior to their
arrival at the filter. Unfortunately, they become clogged, collapse, and
restrict fuel flow. Just an idea.
