Actually Ben I only replied to you privately not to the list so all he had 
to go on was your reply. I'm not trying to be forcefull on this one, but I 
have Bosch training, worked for years at a Bosch repair facility and own 
Bosch technical documents on nearly all forms of the system. I assure you 
that the Bosch regulator with two fuel hoses is essentially the same on most 
cars including the CIS 911's that I work on daily and the 5000's that I'm 
rather familiar with and functions as explained by Andrew and myself. Some 
models have vacuum referance ports and some don't, but all function by 
reducing control pressure by bleeding it into the fuel return to the tank 
(sometimes by way of the fuel distributor, but it still goes to the same 
place).

Reading that I can see that this message may be a victim of emotionless 
text, but you know how easy going I am Ben, please don't take that in any 
harsh or forcefull way. I am just absolutely with zero doubt about my 
knowledge of pre-DPR (differential pressure regulator - WUR-less) CIS.
