Please help. Fuel pump installation problems

Featured Replies

Nothing is ever straightforward with my 94 loyale. I have a few problems and was wondering if anyone has a crafty solution to them. I removed the three 10mm bolts that attach the fuel pump to the underside of the car. BUT all three of the bolts broke off. There is also a nut on the other side of all of them but they are so rusted on I can't get them out. 

 

The other problem i have is that the original fuel pump mounting bracket has a rusted on screw that wont come out either. The new mounting bracket I have does not fit properly so I need the original. I'll attach pictures so you have a better idea of what I'm talking about.

If they snapped off from being stuck from rust, do not even bother with an easy out. 

 

I'm not sure if I would try the weld a washer to the broken bolt trick for this, as they are so small, and upside down.   It is amazingly effective on 8mm and up though.

 

Drill them out is what I'd figure.

 

The rusted screw / clamp thing, just grind off the head and the nut, replace with new.

Do I have to worry about running a drill near the fuel lines?

Cap / clamp them off.  I'd avoid hitting them.

Make sure there isn't any fuel wetting the area.

Otherwise, shouldn't be a problem.

If one happened to be very close to a heat source, a piece of aluminum would work as a heat shield.

Alright thanks Dave hopefully I can get the pump in tonight

As I recall, those nuts are welded on, so it is not corrosion that is keeping them there.

 

Drill out the bolts and retap?  Or just drill and use a nut on the far side.  Retapping will be easier, I think, than trying to put nuts on the back of those bolts. But not every one has a tap.

 

Use lots of antiseize when they go back together. 

 

As for the clamp, just improvise something with a bit of sheet metal, or a big hose clamp or 2.
