The white nylon O-ring is used on quite a few Ford Pumps pressure fitting. You have to stretch them out to install them and they are a one time use.

I am thinking the issue is different knuckles on the dana 60 between a 93 model axle and the later ones. Seems to me that there is difference in the brakes between those axles.
In edit this kind of helps...
Trevor, I have a stock cover on my Dana 60 as far as fit up goes. Call or Email me when ever you are ready. I have plenty of free time for playing with this.
The right place to direct the issue would be more with the injector builder and the tuner. I would be wondering if you had something mismatched if and only if the truck ran real good before and the injectors and tuning where the only changes.
