Defuelling

Defuelling

1. Two defuelling methods

   • Pressure
     • Defuelling using booster pumps
     • 25 - 50 psi
     • Defuel transfer valve is a motor driven valve and interconnects the fuel feed manifold and the refuelling manifold
       • Defuel transfer valve allows fuel flow into the refuelling manifold
       • Check valve prevents reverse flow from the refuelling manifold
     • Preferred method of defuelling
   • Suction
