I had my fuel injectors replaced with Bosch 36# units when I had the STS turbo installed. It ran fine for a while (~2000 miles). Then the fuel pressure regulator failed. I pulled the rails and injectors to replace the regulator myself. The operation was a success, except now my injectors are falling into the intake manifold and out of the fuel rails. I have tried new orings, lubricating the orings, everything I could find on the forums. I then researched some more, and discovered that the original injectors have a groove cut near the top for a clip that holds it to the fuel rail. The Bosch do not have such a groove. Is there a solution out there? I am really frustrated at this point and would appreciate some advice.
Thanks in advance.
