Ok I have the injection pump disassembled in a hundred pieces, I am trying to get parts for it. I have the numbers stamped on the housing yet the little silver sticker is illegeble that one has the info I need to get it calibrated correctly. The rollers and roller plate are worn and blued from heat. Obviously the scavenger side of pump failed and it ran low on fuel and got hot. If anyone has a d-50 with a 4d-55t and can still read that sticker that is what my parts guy needs to order the correct internal parts. Or if anyone knows an available bolt on replacement pump, aftermarket or otherwise that would be calibrated close to original that would be great. Thanks
