The answer lies right there, dude. You're apparently ripping the lower O-ring when installing the new-to-you injector.
Use some Vaseline, finesse and patience to HAND SEAT the injector first. When you finally get around to fastening the cap back on, don't fully tighten one side first. Do a couple/few turns per side at a time.
