Did the factory ever make a Factory water pump? The reason I ask,is 'cause I was in a local U-Pull-It joint,and,I ran into a guy who was stripping a '80 Zepher 4 door. I noticed that the water pump seemed to be a faded Silver in color(NOT painted.....). And so,I asked the guy ripping it apart could I take a closer look at the pump,and sure enough,it was Aluminum. I could'nt find a Ford part# or anything on it,except for a casting letter(and,a few sharp casting seams.....)sooooooo,anybody know about these pumps. Yes,yes,I know the aftermarket DID make them,but Factory?? OO6.
