Where is the fuel pump fuse located in Jinbei Haise?

Jinbei Haise's fuel pump relay and main relay along with the fuse are located in the battery box under the driver's seat. The working principle of the fuel pump relay is as follows: 1. Principle One: When the relay operates, 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. Thus, the relay uses the electromagnet to control the on-off switch of the working circuit. 2. Principle Two: Electromagnetic relays generally consist of an iron core, coil, armature, and contact springs. When a certain voltage is applied across the coil, a certain current flows through it, generating an electromagnetic effect. The armature then overcomes the force due to electromagnetic attraction. 3. Principle Three: The return spring's tension pulls the armature toward the iron core, causing the moving contact of the armature to engage with the stationary contact (normally open contact). 4. Principle Four: When the coil is de-energized, the electromagnetic attraction disappears, and the armature returns to its original position under the spring's counterforce, causing the moving contact to re-engage with the original stationary contact (normally closed contact).
