I wasn't careful when I was tightening the nut for my new fuel pump and snapped off one of the terminal post looks like I need to buy a new fuel pump

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.

Could you use a spring washer to help with the offset?

Can you just ignore the offset by tightening two nuts together on the bolt, keeping clear of the body, rather than tightening the nut down onto the body? Maybe with a locking washer of some sort.....

Thats a nyloc - the insert stops it loosening from vibration.
