Zusammenfassung:	Conventional apparatus for testing fuel injectors are inconvenient, difficult to adapt to different injectors and are quite expensive. The subject apparatus overcomes these problems by providing a testing apparatus which has a fuel manifold with internal passages to an interchangeable adaptor. The interchangeable adapter provides for different sizes of fuel injectors and changes in access to their fuel ports. The apparatus includes visual inspection means that can readily changed to a measuring means for measuring the fuel being injected as well as to continuously observe the injection spray. The entire apparatus is self-contained in a manner that reduces external leakage of fuel during testing and is under control of an electronic controller that simulates engine operation of a fuel injector.
