ABSTRACT:
A continuous deaeration system for use in maintaining a high pressure oil rail of a hydraulically-actuated, electronically-controlled unit fuel injector system free of entrapped air including a tube, one end of which seats in an oil passage leading from the high pressure rail to the front injector of each bank of the engine. The other end of the tube seats within an upper area of the rail, where air may be trapped. The tube thus creates oil flow into the injector from the area of the rail having the air therein, causing the air to be quickly purged through the injector.
