98A54003002000 is a precision aviation maintenance tool, compliant with AS9100D quality standards and FAA/EASA maintenance regulations, designed for the fuel systems of large commercial aircraft.

It serves as a fuel injector disassembly and installation tool, used to safely remove and install fuel injectors during MRO maintenance. It applies controlled, uniform force to avoid damaging the injector's delicate components or the engine's fuel supply interface, preventing fuel leakage, disrupted fuel atomization, or reduced combustion efficiency that would affect engine power output, increase fuel consumption, or cause engine instability during flight.

Made from high-strength, corrosion-resistant aluminum alloy, it operates stably at -45°C to 180°C, and resists wear. Weighing 0.34kg, it has a precision positioning structure, a critical tool for engine fuel system maintenance safety.
