Can’t anyone come up with any type of published article about this (anything but a story from Yahoo that is, I think we have all agreeded not to accept automotive information from Yahoo).I am open to looking this over. I must have changed 200 fuel filters over the last 35 years and I can think of probably 2 that I actually saw paticulate matter run out of when emptied. Sure I can testify to seeing a small amount of rust colored material at the bottom of gas tanks (noticed when changing fuel filters). I think the majority of fuel pumps I have changed over the years went bad due to design errors (ruptured diphrams on mechanical pumps don’t count). Fuel pump failure did happen on CIS cars like VDC describes but never on one of my CIS cars.
