I can confirm that it was indeed my fuel pump, and I have made it through the repair, though it took me all weekend.

KlausC was right - the saddle style tank does make things very difficult, but I did manage to get through it.

Also, the really hard part was that the actual pump itself is very different style/shape than the FWD one. I did manage to get a hold of a used FWD pump (car had (100k miles on it) and rig things together to get it to fit but I wouldn't recommend it. There was a lot of improvising. I only did this because I couldn't get a pump quickly any other way - NAPA wanted $300 and couldn't get it until Friday, and FCP doesn't list the pump separately from the assembly, so it's $400 and 5 days from them. This was something I could do this weekend and didn't cost me very much (I haven't worked it out with the guy I got the pump from but I expect he'll be reasonable. He's kind of got me over a barrel now that the pump is in the car eh?)

If this pump dies or my setup doesn't work well in some other way I'll buy something new.

I've got some pictures so I'll post back later with more details of how this job went. It was a hell of a weekend.
