Steve. Thanks for responding. What is the purpose of the second regulator??
I have section 7.4.2 of the 110 engine manual, which covers the D-jet, and their is no mention of it. The schematic diagram in the Bosch manual doesn't show it and there is, again, no mention. Was it something used on the Euro models ?? My manual is for US 280 models. I have Ben Watsons book on the D-jet and while there is a test for return volume it is taken from the pressure regulator. Could that be what it is for, to control return volume?? Again thanks for responding.
