Product Description
The 643617 is a rigid tube assembly for aircraft fuel-injection lines. This component routes metered fuel from the fuel control unit to injector nozzles on fuel-injected piston engines. Fabricated from aerospace tubing with precision bends and flared connection ends, the assembly maintains fuel system integrity under operating pressures.
Installation requires proper torque on flared fittings, secure clamps to prevent vibration damage, and leak verification per engine maintenance procedures. Verify part compatibility with your aircraft's illustrated parts catalog before installation.
