Task Instructions
1. Clean the bilge area of any sand, stones, or other debris.
2. Remove the lower screen from the bilge pump and set it aside.
Note:
It will not be used unless the strainer in the aircraft is damaged. To bond in a new lower screen of the bilge pump, use 3M fire barrier (201). Wipe excess sealant extruded from pin holes flush with top side surface of bonding flange. Allow fire barrier to cure for 90 minutes before reinstalling the bilge pump.

3. Install the pump body onto the bottom strainer already in the aircraft by aligning it and rotating it clockwise until locked.
4. Cut hose to 42.0”±1.0”, make cut in the center of the flat section. Attach the bilge pump hose to the pump barb fitting and secure with a 3806 CLAMP as shown below. Route the hose as indicated below. Slide one end of the hose onto the bulkhead fitting in the fuselage wall (until flush with the fuselage wall) and the other end onto the bilge pump (until flush with the bilge pump).

5. For the clamp on the bulkhead fitting in the pilot side fuselage skin, clock the clamp such that the screw housing is fully within the following approximate zone, make sure there is a minimum clearance of .125” from the fuselage roll control cable. Tighten clamps until a seal is achieved.

6. Connect D9009J connector on bilge pump to D9009P connector on main wire harness.
7. Test that the bilge pump operates normally.
Verification Method
The procedure is complete when the fuel tank is installed.
