Kudos to Racor - Parker Hannifin. The drain valve to my 30 year old diesel filter and water separator cracked and was leaking fuel into the bilge. After scouring the local suppliers for a replacement I was resigned to buying a new filter ($100 to $150). As a last resort I called Racor to try to find a supplier. Although they haven't made the filter for many years, they immediately identified the filter and knew a current model had the same drain. Best of all they said they would send me one. It arrived three days later. NOW THAT'S SERVICE. Thirty years later they still back their product. Stick with Racor folks. Not some cheap offshore knock-off.
