ABSTRACT:
Method and apparatus for cleaning fuel injector systems of internal combustion engines which comprises avoidance of burns and possible injuries in setting up the conventional system apparatus in the engine compartment. The present method is characterized by setting up the required connections and apparatus at the rear of the vehicle in an area isolated from the region under the vehicle hood. The invention has other advantages. In particular, filter replacement in the isolated area subsequent to completion of the cleaning process is effected by a novel aspect of the method which involves filter removal as a step in the method. In a conventional method the filter is left in place but ultimately replaced, for comprehensive maintenance of the fuel system, as an additional step. Another advantage of the invention is the method of detecting leakage in injector and fuel flow systems and to detect the extent of clogging of individual injectors to determine the need for replacement.
