Posting these photos and diagram of the Piersburg Fuel pump in case anyone else runs into the same problem as I did. i found a photo of when I pulled it apart and springy flap thing is clearly closed.

Not so clear in diagrams…

Mine was definitely open when I rebuilt it- hopefully the cause of problem.
Thanks for all the help.
Will let you know how it goes
