A fuel pump used to remove the last dregs of usable fuel from a fuel tank once the fuel level in the tank has fallen too low for the primary fuel pumps to be able to draw fuel from the tank.
Example Sentences
- "The scavenge pump is designed to remove the last amounts of usable fuel from the CWT and pump it into the left inboard (No. 2) fuel tank. The intake opening for this pump is located very close to the bottom of the tank between the mid spar and SWB2. Although the scavenge pump removes fuel that is unobtainable by the jettison/override pumps, a small amount of residual fuel will remain in the fuel tank that the scavenge pump is not able to remove (unusable fuel). In the 747 CWT, the jettison/override and scavenge pumps are mounted on the rear spar such that the pump motor is external to the tank but contains fuel-cooled windings."
