Table of contents: Fuel capacity 🠇 Fuel pressure 🠇
The fuel pump typically delivers much more fuel than necessary, and the excess fuel returns to the fuel tank through the return line. In fact, the maximum allowable fuel pressure in this system is more than 4 bar. To prevent pressure loss in the fuel supply system, a non-return valve is located in the outlet pipe of the fuel pump. When the ignition is turned off and the fuel pump stops operating, the pressure is thus maintained for some time.
