How is the collector tank replenished?

• A. Gravity-Feed manifold connecting the collector tank to its associated wing tank by a scavenge ejector
• B. Electrical pump from the wing tank
• C. Manual gravity feed valve from the cockpit
• D. Pneumatic transfer line from the wing tank

Answer: (A)

Automatic replenishment of the collector tank is achieved by a gravity-feed path that links the collector to its wing tank, with a scavenge ejector actively drawing fuel into the collector as needed. The gravitational head from the wing tank provides the basic drive for flow, while the ejector creates suction to pull fuel through the line, keeping the collector topped up without relying on an electrical pump or pilot-initiated valves. Relying on an electrical pump would add power requirements and potential failure points; a cockpit valve would require pilot action for replenishment; and a pneumatic transfer line would need a source of compressed air. So, gravity feeding augmented by a scavenge ejector is the effective, automatic method for replenishing the collector tank.
