It is literally always hungry and massively obese, because the normal satiety signaling hormone â leptin â is absent from circulation. Researchers typically use the ob/ob mouse as a model for type II diabetes. When you inject an (obese) ob/ob mouse with leptin, it loses weight and its health markers normalize.
The tank pressure sensor is usually located on the top of the fuel pump assembly.
One thing to remember with a propane tank is that the pressure inside the tank can change, even if a gauge won't tell you how full it is. As the tank cools, the pressure will decrease. As the tank warms, the pressure will increase. If the tank pressure gets high enough, the safety valve will open to let out the extra pressure. This is why you should never leave a propane tank in a hot car, store it indoors, or let it anywhere near a fire.
