Bit desperate are you Gamebowser?
For starters, the classics lounge is one of the quietest on the board, but most of us who come down here pay attention to all of the new posts, so relax. Nobody is going to ignore you.
Secondly there isn't a wealth of diagrams in the AO collective archives. Papajam (who has posted on this thread) usually hangs his hat on AlfaBB -- the site mentioned in the first post on this thread, and he's the one who created most of the diagrams that everybody on the Internet uses. It might be worth sending him a PM to see if he has something in his files which could help you.
I guess what I'm saying is the BB is the place to go if you really need some old diagrams. If they aren't already posted there, often the BB folks can supply diagrams on request, if you ask them nicely. While I hate to drive traffic away from AO (which happens to be my online home), I do suggest you go and register on the BB. The added benefits to getting to know the BB are that most of the posters are based in the States (whereas AOers are mainly British and European) and as such, they can direct you to local parts sources. Also, the focus of the BB is older Alfas. Here it is newer production cars.
I see you also made a request (on another thread) of Jamie about diagrams he may have. Sadly Jamie is no longer a member here, but if you're looking for him, you can try the forum on Jim's Spider Page. He's a moderator over there. If you register on that board, please tell him who sent you in that direction.
Now if you care to share exactly what you are trying to accomplish with your fuel pump, the odds are pretty good that you'll get a solid answer from the crew here. There are some pretty knowledgeable and trustworthy folks here. Sadly I'm not one of them.
My expertise (if you want to call it that
) is limited to precisely one Alfa Romeo -- mine -- and I have no desire to extrapolating situations from my car to any other car. The odds are pretty high that I'd get things badly wrong.
