Everything fine,i was driving the truck for a pick-up and back to my yard,i left the engine to idle for 3 minutes and start shaking the engine and worst then befor to replace the 3th injector. Did again the leak test and i got bubbles again but now i didn't bar it to find out exactly witch one is leaking.when i did the first time leak test it was leaking only between A and B.thank you in advance

It may be that you changed the wrong injector. Don't know for sure, waiting for knowing guys

Hello all, new member here, just wanted to mention the tool that Cummins recommends for the injector leak test is a manometer, you can make one cheap using 1/4" vinyl tubing and it would make even small air leak noticeable when the water height changes in the opposed columns, Google DIY manometer

There a few guys making them on here for other members... They are not cheap if bought from Cummins, that is for sure.

Now my truck runs good,i ended to replace all 6 injectors cuz i found out 4 of them were leaking.
