This may be a fool question , but did you replace them all at the same time?

Are you using Alliant brand o-rings? Got the injectors seated all the way and torqued down properly? Lubing them up good before the install?

Not to derail, but what does the truck do when an o-ring is blown?

Drinks all of its oil. Or oil in the fuel bowl.

Is the injector cup in good shape? any cracks or scores that might cause the orings to rip?
