Googled for "0 280 161". It's described as a "fuel damper" or "fuel dampner". Many hits.

0 280 161 015 = Porsche 944 part
0 280 161 006 = 1982-1988 BMW 528e M20

Bosch don't list that part for your car in their efi_techservice.pdf file though.

I'm not real clear where was fitted on your car - is this part #33 on this diagram?

That's described as a "vacuum limiter", but it seems to go more or less where you described it, and look fairly similar...

All your pressures seem quite high. Bosch quote 2.1 + 1.1 bar opening pressure = 2.1-3.2 bar for my injectors. I make that a maximum opening pressure of 47 PSI, so yours are right at the top limit.

What do you mean "take the shims out to get to 50" for the WCP? The shims in the pressure regulator are to adjust SYSTEM pressure - you need to move the plug in the WUR to adjust WCP?
'77 S with '78 930 power and a few other things.
