Product Description
The 4003ZE is a fuel tank suction relief valve for ATA 28 fuel system protection. This valve opens under differential pressure to prevent vacuum damage in wing tanks during fuel consumption and descent operations. Installed in suction-relief circuits on Dassault Falcon 20-F5 aircraft and similar platforms.
The valve maintains tank integrity by venting excess negative pressure while preventing fuel spillage. Installation requires verification against the aircraft's Illustrated Parts Catalog and compliance with maintenance manual procedures and FAA AC 43.13-1B acceptable practices. Perform leak checks after installation to ensure proper sealing.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
