The invention provides a pressurization test clamp for an aircraft fuel system, and belongs to the technical field of aircraft system debugging. The clamp comprises an air supply switch, an adjustable pressure reducer, a three-way connector, a one-way valve, an anti-explosion pressure gauge, an air source mouthpiece, an airport connector mouthpiece, a short hose, a long hose, an air source mouthpiece plug cap and an airport connector mouthpiece plug cap. The device is used for precisely debugging air supply equipment on the ground of the fuel oil system, is simple in pressure adjustment operation, ensures that pressurized air with different pressures is provided for the system, has the characteristics of being simple and easy to mount, convenient to dismount and the like, realizes single-person ground air supply work, reduces multi-person work, and has a short clamp preparation period. The aircraft fuel system debugging air supply pressurization requirement can be completely met, the requirement for one operator is reduced, and preparation work can be completed by one operator within a short time; in the debugging process, pressure adjustment is simple, pressure adjustment is accurate, and the accuracy, high efficiency and convenience of the innovative test clamp are exerted.
