Fuel Distributor
Fuel distributor has been changed from previous CIS units. System pressure regulator piston and pressure compensating valve have been deleted. Differential pressure adjusting screws and compression springs have been moved to lower chamber. Additional strainer is installed in front of differential pressure valve. Pressure on top of control piston is equal to system pressure. Fuel supply, return, and cold start valve lines are arranged differently. These connections vary depending upon engine or manufacturer applications.
