Early Gas Engine Fuel Injector Back Flush Cleaning Kit

Works on Bosch MFI and CIS mechanical fuel injectors from the late 1950's to early 1990's. Will NOT work on electrically operated fuel injectors.

With these old gas fuel injectors, sometimes you just have to "back flush" the insides to restore them to peak performance. There is no guarantee that back flush cleaning will restore every old gasoline mechanical fuel injector. Some are just plain worn out.
