Refer to the manufacturer’s specifications for precise specifications. Both of these conditions can lead to engine failure. The injector with less leak-off is possibly injecting excess fuel and that cylinder may be experiencing knocking. In general, the injector with a greater leak-off is injecting less fuel, and therefore that cylinder is producing less power. It is a comparative test where each injector is connected to a calibrated measuring flask and the engine is operated through its range for a set period and the leak-off is read and compared to the rest of the injectors. The DM13-T175 common rail diesel injector return flow testing or leak-back test kit is designed to measure the fuel leak- back from each individual injector to identify mechanical issues within the injector. For visually testing injector flow rate via return lines - Allows for simultaneous testing of up to 6 injectors.
