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.
1 Check the air pressure in the water tank by using an accurate air pressure gauge (such as a dial type or digital tire pressure gauge) to measure the air pressure at the schrader valve on the water tank. 2  The tank pressure should be within 10% of the original factory water tank pressure setting.
