ABSTRACT:
Pressure filling of an elevated liquid reservoir from a blind servicing location is successfully accomplished by a gravity drain extending from a reservoir vent overfill to the servicing location. A dust cap serves to cover the pressure fill hardware fitting and to provide a primary seal for the drain. A second drain seal is closed by engine operating pressure and opened by application of the pressure fill hardware fitting.
