Boost leak from fuel injectors.

So I built a boost leak test rig today installed and tested the car, found a few leaks from vacuum lines fixed those. Also found that the fuel injectors are leaking(all 8 of them) on the intake. Went to the autoparts store and picked up a new set of o-rings and got all to seal except for the front one on the driver side. Swapped injectors same thing, pulled it all apart verified the hole was clean round not scared or cracked, even sprayed it out with some starting fluid put it back together still leaks under pressure. It is not leaking under vacuum but with positive pressure its substantial, I sprayed some soap bubble on it and it doesn't bubble it blows the water/soap solution away.

Curious if anyone knows if there is an over sized o ring that I can run or other solution to this?
