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.
On the fuel rail, you'll find the place where a fuel pressure gauge adapter fitting can be installed. Look at the photo in the image viewer and you'll see that. 2. Screw in the appropriate adapter from your selection of brass fittings in your fuel pressure gauge set.3. Connect the fuel pressure gauge to this fitting.4. Have your helper crank the car while you observe the fuel pressure gauge. 5. You're going to get one of two possible results, and they are: 1.) The fuel pressure gauge will register 30 PSI, or. 2.) The fuel pressure gauge will register 0 PSI.OK, now that the testing part is done... let's take a look at what your results mean: CASE 1: Your fuel pressure gauge indicated 0 PSI This confirms that the fuel pump is not activating and supplying fuel to the fuel Injectors.. Connect the fuel pressure gauge to this fitting. 4. Have your helper crank the car while you observe the fuel pressure gauge. 5. You're going to get one of two possible results, and they are: 1.) The fuel pressure gauge will register 30 PSI, or. 2.) The fuel pressure gauge will register 0 PSI.
