The paper considers the methodology for confirming the quality of manufacture of capillary phase separation element of the infill fuel tank intake device of the space liquid rocket propulsion unit during the acceptance-delivery stage of the tanks tests. The stability of the capillary structure is estimated by the constant value of the capillary retention capacity of the mesh material of the separation screens of the capillary phase separation device at all stages of production and testing of the fuel tank with an internal capillary intake device. The stages of emptying the internal tank intake device from liquid during experimental determination of the values of the capillary retention capacity of the separation screens of a two-stage phase separation device in the composition of a fuel tank are considered. The hydraulic test scheme is provided and the approach to the selection of the fluid used in the tests is recommended. The calculated dependencies on calculation of capillary retention capacity values of porous-mesh materials of separation screens of the gas separation device based on experimental data are presented. Test results are analyzed.
