Sounds like you have diagnosed it correctly.
Vibration is one of the things that can crack a Fuel Injection Hard Line. All of the Broken clamps will also need to be replaced to help prevent it from happening again.

The Rubber Band that goes around the Injector is there so that when they rebuild the Injectors they can use any upper Injector Body and not have to worry about how many Bar of pressure is stamped on the Body; the Band covers that up.
The Rubber Band also has the Rebuilt Injector Part Number on it.
That Rubber Band does not seal any thing.

I would have left the Injector alone until I had the new Fuel Injection Hard Line to see if that stopped the leak.
Sometime when you take an Injector apart and put it back together without lapping the Flat surfaces that leak between the Injector Nut and the Upper Body.
