The relatively-new pump that I was using flows approx 750 cc per 30 sec (should be 900-1000 cc) and no pressure (turns out that could be another problem and not the pump); I have not tested the other older pump. You are welcome to buy one of these pumps, but--I'm pretty sure you don't want to buy my problem(s)! Better would be to find some shop that rebuilds the Bosch pump for MFI and guarantees their work. I suspect there are a lot of Porsche-types who would appreciate that service

These can be cleaned and rebuilt. I remember a thread on Pelican that explained how.

I found the article to make your used fuel pump run like new...

Even better, lets just add the content here:

The electric fuel pump on my 1970 e was inop after sitting for 10 years. Based on the junk in the tank, I figured the pump was beyond repair. So the fun part comes, I get to take it apart to see how it runs, certainly can’t hurt it. Bottom line, after taking it apart replacing three orings, acquired from the local hardware store, and de-gunking, it now is humming and pumping the correct amount with no leaks.

Toughest part of the disassembly was undoing the “stakes” and prying the outer body from the top section. Haynes says these are not repairable, we’ll see. If any else attempts an overhaul consider it a last resort and be prepared to buy a replacement. Here are some pictures of the disassembled cleaned up unit
