Just finished installing an upgraded branch tube adapter.
I'm wondering whether I screwed up my HPOP.
I followed the instructions, which is to place the HPOP in the vice and replace the old branch tube adapter with the new one that doesn't have an STC fitting. This went well except I tried to turn my pump while it was in the vice and it wouldn't budge. I don't know whether this is normal, since, I didn't try to turn the pump outside the vice.
At this point I'm worried that I may have ruined the pump by tweaking it in the vice.
Does this sound possible? I have a very large vice that has a lot of clamping pressure. Thinking back on it now, I should have tried to wedge the pump into the vice in a way that held it, but did not required tightening down the vice so much.

Does anyone know what the failure mode is for the HPOP?
Is it going to send metal shavings through my engine if it fails?
How soon will I know whether it has failed and will it be too late to recover from, without ruining my motor?

Has anyone experienced anything like this?
