then the next step(s). are to...

pull all the fuel .lines from the injector feed tubes .. loosen them all and re-torque them to spec. - re-install the lines, get the air out fo the system, and then do the leak test again. Maybe you get lucky and its only a feed-tube issue.

- After that, its capping off injectors up to 3 at a time with a cap-off kit.
