Where is the high-pressure fuel pump located in a Corolla?

[McAdam]

Fuel pump is installed inside the fuel tank, and the relay is placed in the large fuse box on the left side of the engine compartment. The main functions of the gasoline pump relay include amplification, allowing a very small current to control a high-power circuit, and expanding the control range. Additional information: Typically, when the relay is in operation, the electromagnet is energized, pulling the armature down to make contact between D and E, thereby closing the working circuit. When the electromagnet is de-energized, it loses its magnetism, and the spring pulls the armature up, cutting off the working circuit. Therefore, the relay is essentially a switch that uses an electromagnet to control the opening and closing of the working circuit.
