APU Fuel Transfer Pump Removed
(Appendix B, Section 1II, Item 1)

Notch the pump cover and body with a file so they can be reassembled in the same relative
positions and remove the six screws (1) to remove top cover (2).
Tap the body with a screwdriver to separate the two parts. Do not pry them apart; this would
damage the diaphragm (3).
Lift out the diaphragm assembly (3) and diaphragm spring (4).
