Maybe a stupid idea but if you're careful could you not try soldering the terminal to what remains of the stud? Your gonna scrap the pump now I guess so maybe worth a try.

It's possible but I have no idea how far I can safely drill down into the broken stud on the fuel pump side. Also finding a small enough replacement stud to screw into the newly drilled hole and have it tapped out to receive new stud. |

Given where it is, the difficulty of replacing it, and the consequences of it failing, I would be inclined to just chalk that one down to experience and replace it.
The max torque for an M4 bolt is around 2Nm, or 17 inch-lbs so barely anything really. |

This is the nut for the negative post on the fuel pump and it looks like it has a nylon insert?
Here is my attempt at fixing my broken fuel pump stud. I was able to drill and tap the hole. I was able to get stainless steel screw, washer and nut for the repair. Unfortunately I wasn't able to get the hole drilled completely straight . Got the head cut off and now I'm wonder if this is going to be a problem as this is not sitting straight and could cause a problem? Quote:
Yeah I know it doesn't need to be super tight for that nut. I guess I was super excited that I finally got everything I needed to start putting my new fuel pump back together and was in a hurry and over tighten that nut and it snapped Last edited by Audifan; 9th November 2020 at 09:49 PM.
