The flex injectors flow more fuel. The orings are the same iirc. If you only have 1 leaking id bet it got cut during assembly.

I had a couple get cut always keep extras the trick is lube the o ring put all the injectors in the rail first while it’s off then put them in the intake

As stated before, I bet that leaky injector is due to a bad O-ring. I would recommend using Vaseline when installing so they don't get pinched and tear. Good Luck
