Have you noticed that the pressure regulator below the Fuel Distributor has a 4mm Allen recess in the back?
It looks like this may be some kind of adjustment or for compensation. There is no mention of such an adjustment in the Service Notes! They tell you the adjustment is carried by changing quantity of shims.
Could it be just to facilitate removal/installation of the plug? Is the outer nut just a "jam nut"?
Any ideas?
