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.
The fuel pump can be located in the fuel tank or external to the tank. The fuel pump provides a high pressure feed to the fuel rail that contains the fuel injectors. On the fuel rail there is a pressure regulator that limits the fuel pressure to 39-45 PSI and maintains a constant pressure.The pressure regulator has a vacuum line that connects it to the intake manifold. Any excess fuel leaves the pressure regulator and is returned to the fuel tank.n the fuel rail there is a pressure regulator that limits the fuel pressure to 39-45 PSI and maintains a constant pressure.
