98D54003000001 is a specialized aerospace engine fuel system pressure calibration tool, compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 series turbofan engines. It is used to calibrate the pressure of the engine fuel supply system during maintenance, ensuring the fuel delivery pressure matches the engine's operating requirements across different flight phases, which is critical for maintaining accurate fuel supply volume, optimizing the fuel-air mixture ratio, and avoiding combustion instability or excessive fuel consumption.

Made from high-strength, pressure-resistant stainless steel with a precision pressure sensor, it operates stably in -15°C to 105°C workshop environments. Weighing 0.69kg with a quick-connect interface, it can complete pressure calibration in 2 to 3 minutes, with a calibration accuracy within 0.5 psi. It is an essential tool for engine fuel system MRO work.
