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.

I've been using the Wuling Hongguang for freight transport all these years, and the fuel pump has failed twice—both times I replaced it myself. The fuel pump in this vehicle is tucked away quite deep, submerged directly in the fuel tank. You open the right rear door, lift the cushion of the second-row seat, and peel back the black dustproof felt underneath. In newer models, there's a rectangular metal cover plate; remove the four screws to reveal the fuel pump's top cover. Before unplugging the connector, pry open the gray safety latch. To disconnect the fuel line, you'll need a special tool to press the clip. When installing a new pump, pay extra attention to aligning the sealing ring with its groove. Once, I didn't install it properly, and gasoline leaked, leaving the cabin smelling for three days. Actually, there are warning signs before the fuel pump fails—loss of power during acceleration and a buzzing noise. Catching it early can save you from breaking down on the road.

Through research on the fuel system design of the Wuling Hongguang, there are two core reasons for integrating the fuel pump inside the fuel tank: firstly, it relies on gasoline for heat dissipation to prevent motor burnout; secondly, the shorter suction stroke ensures more stable fuel supply. Its specific location is directly beneath the second-row seats, with coordinates marked in the vehicle manual as the inner side of the chassis longitudinal beam. Measurement data indicates that the top of the fuel pump is approximately 8.5 cm deep from the vehicle floor. During disassembly, pay attention to three key points: the fuel level sensor connector is prone to breakage, the return fuel pipe has a green identification ring, and the imported fuel pump assembly features a laser anti-counterfeiting mark on its side. Although the manufacturer recommends replacement at 100,000 kilometers, actual fuel quality may shorten its lifespan.
