It is not too hard to make a bench injector cleaner. Does require some
electronic knowledge (except for CIS injectors) to wire it up. Some heavy
cleaner like BG in a tank with a high pressure fuel pump like on a vanagon
or certain earlier VWs and a line to feed the injector with a pressure
regulator and return to tank and then a drain from the spray area back to
the tank. (the spray area must be sealed shut from sparks or air). Just
like on the engine.
The danger is that fine mist flammable materials like cleaners can become
explosive if at the right air mixture and a spark gets in the system.
