Perkins 1000 Series Engine Fuel Injection Pumps Self Vent Feature

New CAV DPA and DPS fuel injection pumps which will automatically eliminate air from the pump have been introduced on some engines. These pumps have a vent pipe (A1) fitted between the top of the pump and the atomiser leak-off pipe. Vent screws are not fitted to these pumps and connections or plugs need not be released to eliminate air from the pump.
