The starting point for the experiment shown here is a defective injector. As you can easily see on the Internet, the market for used or rebuilt injectors booming (2017). The prices tumble, which of course makes them even more attractive compared to new ones.

If you now buy from a supplier who does not insist on returning your old injector or forfeit the deposit and save shipping costs, you have the one shown in the picture above possibility. You unscrew the injection line to the defective injector and turn it so that the freshly acquired is injected into a glass jar.

If you want to be extra careful, do the first test without connecting to both the old and the new controller (Video Part 1). Then you can see if the injector is tight. Now connect the electrical supply line to the 'new' injector, always switching off the motor in between.

Granted, in the video below you can see a lot of fog, but at least there is certainty of a good atomization. Incidentally, if you leave the return line on the old injector, you should expect in regular episode drips from the corresponding opening of the 'new' nozzle. For further tests, of course, it must be installed, registered with the control unit and driven.

Overall advantage: If one of the tests is not passed, you can send it back within the set time limit. 04/17
