Fuel injector leak down.
 

Putting my fresh 509 back together, all new rotating assembly with m-3 back together. I bought bigger fuel injectors, installed in custom rail. I did a bunch of SS lines so I figured I would pressure check to make sure. I am all good with all the lines but I am dropping about 3 Lbs. a minute. I can hear it though the runners in the intake manifold. I am having a hard time believing new injectors would be leaking? Could some be open until power to them?? Any help would be great.



Thanks, Dave
