Where is the fuel pump located in the Wuling Hongguang?

The fuel pump of this vehicle is installed inside the fuel tank. Replacing the fuel pump requires removing the fuel tank. Below is relevant information about fuel pumps: 1. Diaphragm-type fuel pump: The diaphragm-type fuel pump is representative of mechanical fuel pumps, used in carburetor engines, and is generally driven by an eccentric wheel on the camshaft. The diaphragm-type fuel pump features a simple structure, but due to being affected by engine heat, special attention must be paid to ensuring fuel delivery performance at high temperatures, as well as the durability of the rubber diaphragm against heat and fuel. 2. Electric fuel pump: Unlike the diaphragm-type, it is driven by electromagnetic force to repeatedly move the pump diaphragm. This type of electric pump allows for flexible installation locations and can prevent vapor lock. The main installation types of electric fuel pumps for fuel-injected engines include being mounted in the fuel supply line or inside the fuel tank.
Last time I helped my friend repair his Wuling Hongguang S, I specifically took a look at the fuel tank location. The fuel pump is securely fixed inside the tank, and you can feel the circular fuel tank cover plate by lifting the rear seat base. You need to unscrew about a dozen screws to see the entire black plastic fuel pump assembly, whose bottom suction port is immersed in gasoline like a filter. However, I should remind you that models after 2014 have an additional inspection hole under the rear seats, so you don’t need to lift the entire tank like with older models. If you’re doing it yourself, remember to disconnect the negative battery terminal first to avoid sparks when removing wires. Also, it’s only safe to operate when the fuel level is below one-third, otherwise, fuel spillage can be very dangerous.
