The fluid tank receptacle 38 includes a receptacle body with an opening 48 therethrough, a bumper 50, a retainer 52, and a cage 54. The opening 50 is sized to receive a fluid tank 56, such as, for example, an oxygen tank, therein. The retainer 52 is secured to the receptacle body and is configured to couple the cage 54 to the receptacle body and movably couple the bumper 50 to the receptacle body 46. The cage 54 includes a plurality of cage supports 60, a support coupler 62, and a plurality of springs 64. The spring 64 is located in the cage support slot 70 and biases the cage 54 toward the storage position. It should be appreciated that the weight of the fluid tank 56 can cause the spring 64 to compress. When the fluid tank 56 is removed, the spring 64 biases the cage 54 toward the storage position.
