Abstract
A fluid flow system for delivering a fluid selectively from a supply tank and a scavenge tank to an internal combustion engine. The system includes pumping means for normally supplying the fluid from the supply tank to the engine and valve means for closing the output of the supply tank upon the presence of any fluid within the scavenge tank such that the pumping means supplies the fluid from the scavenge tank to the engine.
