COMPONENT DESCRIPTION
Ribs 1 and 2 form a Collector Box around the wing tank
fuel pumps.
Clack valves at the bottom of rib 2 permit fuel to
enter the box but prevent it draining out again.
This ensures a fuel supply at the pumps during wing
down manoeuvres.

COMPONENT DESCRIPTION
A float operated arm opens or closes this valve
depending upon the fuel level, to permit air to be
vented.
Valve also opens when:
- inward pressure differential is 0.5 psig
(0.0345 bar) with a full tank.
- outward pressure differential is 1 psig
(0.69 bar) with fuel level below float.
