A liquid transfer assembly includes a housing that has a supply port, a return port and a fill port each extending into an interior of the housing. A shut off valve is movably integrated into the housing and the shut off valve is movable between a first condition and a second condition. A trigger is movably integrated into the grip and the trigger is in communication with the shut off valve. The shut off valve is actuated into the second condition when the trigger is depressed. An inertial pump is movably disposed within the housing and the inertial pump is charged with a handle to pump a fluid in a first container into the second container when the trigger is depressed. A priming pump is integrated into the housing for priming the inertial pump when the priming pump is manipulated.

A sustained drain system circuit and a sustained drain quality control system are constructed in which no mechanical or electrical driving and control mechanism is required at all, siphoning automatically occurs when some volume of urine is retained in the urinary bladder by the mass of urine, its potential energy, intrinsic pressure of filling and contraction of the urinary bladder, and abdominal pressure, and sustained drain continues even with a portion with a height difference higher than a drain source. In the sustained drain system circuit, a fluid is caused to be sustainedly drained by siphoning from an intracorporeal elastic closed space that can extend and contract as a drain source. The circuit is a siphoning circuit in which an inner diameter of a pipe space is designed so that a siphoning volume condition is satisfied and the fluid is drained as filling without a gap.

A siphon priming device that may be releasably and sealingly connected with a first fluid container and usable to cause a liquid to be transferred from the first container into a second fluid container. Using the properties of the first container one may gently squeeze the container to initiate the siphon then remove the pressure and the siphon continues. The first container may comprise a liquid fuel can and the second container may comprise a fuel tank of a motorized vehicle, e.g., boat, car, ATV, cart, plane, motorcycle, etc. In use, the siphon priming device enables simple, rapid, and safe transfer of liquid fuel from a fuel can into a motorized vehicle.

The fuel recovery system is a mechanical structure. The fuel recovery system comprises a station structure, a control circuit, a pump, and a vehicle. The control circuit and the pump mount in the station structure. The vehicle further comprises a fuel reservoir. The fuel reservoir contains the fuel used to power the vehicle. The fuel recovery system pumps fuel out of the fuel reservoir for storage. The fuel recovery system compensates the vehicle owner for the removed fuel through a transaction.

A fuel can adapter is designed to be used with a fuel can having a neck that is internally and externally threaded. The fuel can adapter includes a plate having external threads for engaging internal threads of the neck, the plate including a hole. The adapter includes a sliding tube mounted to slide within the hole in the plate. The adapter includes an elbow mounted at an upper end of the tube, the elbow including an outlet. The adapter further includes a protrusion extending from the plate beside the hole. The elbow bears against the protrusion to exert a torque on the plate that threads or unthreads the plate from the neck of the fuel can.

A gasoline transfer system generally includes a gasoline diverter assembly, a transfer assembly, and a coupling. The gasoline diverter assembly is mounted in a fueled vehicle and includes a conduit operatively connected to a fuel system of the fueled vehicle. The transfer assembly is designed to conduct gasoline diverted from the fueled vehicle to a fuel-deficient vehicle, wherein the transfer assembly includes a hose having a first end operatively connected to the gasoline diverter assembly and a second end insertable into a filler pipe of a fuel-deficient vehicle. The coupling includes a first member attached to the first end of the hose and a second member mounted in a wall of the fueled vehicle and detachably connected to the first member, wherein the second member is connected to the conduit.
