Looking for this part that plugs into the electric fuel pump. When taking it off to get to the fuel pump one of the prongs broke off. Anyone have a spare one or know where I can find one of these?

 

You have a few options, possibly your local auto parts supplier may just have one, your local GM dealer may have one and it is possible other GM divisions use the same connector, and maybe a salvage yard may have something from either a Buick or other GM car that uses the same plug.
If you are able to solder a nail of the same size to the wire remaining in the plug , it just might work. You didn't specify the year of the Buick and that might have a bearing on the availability. I know the nail thing sounds crude, but in a bind , if it will do the job, go for it ! You can always use RTV sealer to seal the plug when done.

 

Thanks Hanky. It is a 1969. Do you have any idea what the proper name for that would be other than electronic fuel pump connector?

 

I don't know what else they would call it other than the external plug in connector for the fuel pump on a 69 Buick, Roadmaster, super, special etc. I would think all models had the same plug.
