Where is the high-pressure fuel pump located in the Corolla?
1 Answers
The high-pressure fuel pump in the Corolla is located inside the fuel tank. Here is an introduction to the high-pressure fuel pump: Function: It draws fuel from the fuel tank, pressurizes it, and delivers it to the fuel supply line, working in conjunction with the fuel pressure regulator to establish a certain fuel pressure. Structure: The high-pressure fuel pump consists of an electric motor, a pressure limiter, and a check valve. The electric motor actually operates within the fuel inside the pump housing, but there is no need to worry, as there are no ignition sources inside the housing. The fuel lubricates and cools the motor. A check valve is installed at the fuel outlet, and the pressure limiter is located on the pressure side of the pump housing, featuring a passage leading back to the fuel inlet.
