send them back in. Ok how do you figure a fuel leak? Not my first set of injectors i have changed. I did every thing like is should be then took it apart and did it again. I have a inch and a ft pounds torque wrench I did the injectors down to 89 in and the tubes to 37lbs and 22 lbs for the lines . I heard the snap of the injectors and the balls up in the tubs and had the snap then to.
I'm thinking I got a pice of dirt or something and one not running right now
