A delivery and storage system for cryogenic fluids features a vehicle mounted dispensing system including a bulk storage tank that feeds cryogenic liquid to a sump containing a pump to pre-cool the pump. The pump feeds cryogenic liquid to another sump containing a meter so as to cool the meter. A valve selectively routes the cryogenic liquid from the meter sump to the bulk storage tank as the meter cools down. When the meter reaches operating temperature, cryogenic liquid is directed through the meter to a dispensing hose. The cryogenic liquid is dispensed into a liquid cylinder. The liquid cylinder features an automatic shut-off device to reduce the flow of the cryogenic liquid into the cylinder when the cylinder is full. The inner shell is held to the outer shell at the top by a combination stainless steel hose and composite cylinder neck. The bottom of the inner shell features a pair of pins which are supported by a strap across the bottom portion of the outer shell interior.

[ What is claimed is:] [1.] A system adapted to be mounted to a vehicle for storing and delivering cryogenic liquid to a use point comprising:a) a bulk storage tank containing a cryogenic liquid;b) a sump containing a pump disposed below the level of said storage tank;c) a pump supply line connected between said bulk storage tank and said sump so that the cryogenic liquid flows by gravity to said sump so that said pump is submersed in the cryogenic liquid;d) a meter sump having an inlet, an outlet and a meter disposed therein;e) a meter supply duct connected between said pump and the inlet of said meter sump so that the cryogenic liquid is pumped to the meter sump to cool the meter;f) a recirculation control valve in circuit between the outlet of said meter sump and said bulk storage tank so that the cryogenic liquid flowing through the meter sump may be directed to the bulk storage tank while the meter is cooling down and thereafter redirected through the meter; andg) a dispensing hose connected to said meter so that cryogenic liquid entering the meter flows through the dispensing hose to the use point.
