How to use the Delphi high pressure diesel tester

The Delphi YDT850 high pressure tester is possibly the no.1 tool your common rail diesel (CRD) specialist doesn’t want you to own.

Because you can test the CRD pump without removing from the engine. When the engine doesn’t start and you have low or no rail pressure, you have the tools to test the output fuel pressure of the pump. This kit also incudes adaptors to test rails and injectors. Why waste hours removing components to have it professionally tested when you the trade professional can do it yourself.
