These rails and injectors and have been in the car for years. I had to take the rails off to replace the intercooler so putting it back together I needed new o rings and this what's happeningDid you verify the rail and injector sizes? Looks like either the rail size is too small or the injector size is too large for that fuel rail application.
Bosch 105lb injectors with fore railsWhat rail is that? What injector is that?

Ok, I just tightened it down. It’s way more than 89 inch pounds but now the rails are tight.The fuel rails should not be moving around. If the bolts are torqued down and they are then your bolt must have bottomed out or is cross threaded. If the bolt had seated down flush on the rail mounting tab and was then torqued down the rail would not move.
