PURPOSE: A device for testing a common rail fuel injector is provided to precisely check a function of an injector while bubbles are not generated from testing fluids in a measurement tube. CONSTITUTION: A device for testing a common rail fuel injector comprises a body, a measuring unit(200), a fixing unit(300), and a common rail(400). A testing fluid tank connected to a high pressure pipe, a lower pressure pump, a testing fluid filter, a low pressure control valve for the testing fluids, a motor and a high pressure pump are formed in the body. The measuring unit comprises a measuring tube(210), which measures the amount of the testing fluids sprayed to an upper part of an injector. The fixing unit comprises a socket(310) for reducing partial pressure and a backless socket(320). The socket for reducing the partial pressure reduces the partial pressure of the testing fluids. The backless socket collects backless fluids discharged from the injector. The common rail is horizontally placed near the fixing unit, and comprises a pressure sensor and a high pressure regulator.
