Abstract: A system 10 fluidly connects a bulkhead B to a portable transport using a flexible fill line or liquid hose LH. The system includes a coupling 12 for separating the liquid hose LH from the bulkhead B during an inadvertent pull-away. An arm 24 is pivotally supported by the bulkhead B, and a support plate 36 is supported at the upper end of the arm 24. A release disk 50 is normally supported by the plate 36, and in turn supports a saddle 42 for supporting the liquid hose LH. Three circumferentially spaced pins 38 function as retaining members to support a release disk 50 on the plate 36. The components thus function to prevent the discharge end of the hose from dropping onto the ground. During a pull-away, at least one of the coil springs 64 associated with each release pin is compressed, thereby releasing the disk 50 and allowing both the saddle 42 and the liquid hose LH to become disconnected from the arm 24.
