I thought that I had a CIS problem before!

neat. Didn't realize that a fuel distributor looked like that. the rings look all wrong, but it probably worked for a while. good luck and I'll check back to see what happens.

OK,
One thing led to another and I didn’t get around to calling Bosch Australia. My friend however did drop me off a selection of o rings.
I cleaned everything up pretty good and put the new o rings in it, glued it together with some type of Loctite stuff. I took it home and connected it up pretty much straight away.
I turned the fuel pump on and straight away it was better than it was when I started this project because there were no leaks.
I then put the injector lines into 6 separate containers and lifted the main sensor plate. They all delivered fuel. I later measured them and it was 103, 103, 103, 100, 100, 105 milliliters in about 25 seconds.
Just remember the car’s not running yet!!
Does this tolerance sound acceptable??

I would think the variation is acceptable (5%) at this early stage, but how do you know the absolute qty is correct? How are the spray patterns?
Try to start it and see what happens, the worst that can happen is it floods. Make sure you have a popoff valve on the airbox since it will almost certainly be backfiring as you go through the process. Have you tested control pressure yet? Set the idle mixture so that there is no fuel coming from the injectors with the engine off, and so that some fuel flow starts just as the flap is lifted. That should get you going unless anybody else has a more correct baseline procedure.
