Sounds like a good idea. Have you really eliminated a major vacuum leak as the problem already? I have not had to work on the fuel system on mine yet, so not much help from me.
I did pull the pump out of my parts car the other day and got a couple pics. This Tech article is pretty straight forward:

A few notes: Take your time disconnecting the vents hoses and wires, don't force anything - It should all come apart fairly smoothly. I broke part of the fastener that holds the fuel lines to the pump, Pulling too hard before releasing the fastener all the way. The pump housing came out easily from mine with one hand grip and a twist.

Here's what came out.


I expect that the pump you purchased will go inside the housing. Note the O-ring that fell to the bottom.
