Fuel Distributor
The fuel distributor unit differs from the standard CIS system as follows: System pressure regulator piston and pressure compensating valve are no longer installed. Differential pressure adjusting screws and compression springs have been moved to lower chamber. Additional strainer is installed in front of the differential pressure valve. The pressure on top of control plunger is equal to system pressure. Fuel supply, return, and starting valve connections are rearranged. SeeFig 2 .
