Bosch 044, ground problem

[eder-loco]

Well i was installing the nut back on the Ground side of the pump. and for some reason it just stripped!!

I tried removing the stud, but its not working.

Anything similar ever happened to any of you guys? any ideas of how to ground the pump?

If you can retap that stud to a smaller size diameter then a matching nut ....
