REPRODUCTION. You are purchasing a fuel and vacuum pump repair kit for AC Type 4074 fuel pumps. This is for late 1953 models that have fuel pumps that do not have a glass bowl. The image is just a representation of the kit, you will receive the correct parts for your pump. Used on original fuel pump GM Part # 5593212.
This kit requires you to reuse the original diaphragm rod in the pump. This will require a hydraulic or arbor press in order to disassemble the original diaphragm. Do not grind off the machine pressed end of the diaphragm rod that holds the diaphragm saucer assembly together. There will not be enough remaining metal for reassembly if the machine pressed end is ground off.
If your pump has ever been rebuilt before, some additional steps may be required in order to use this rebuild kit.
For full instructions please see the instructions tab.
