What is the method for disassembling and assembling the fuel pump of Changan CS75?

First remove the seats, take out the middle seat in the right rear and the last row of seats. There are three pipes and one wiring harness secured with screws. Disconnect them in order before removing the screws. Take out the fuel pump. It might get slightly stuck during removal, so proceed slowly. Use a flat-head screwdriver to remove the base. Then first remove the filter screen - there is a small clip that can be detached using a flat-head screwdriver. After replacing the pump core, reassemble everything.

I've disassembled and installed the fuel pump of the Changan CS75 several times myself. It's quite interesting but requires caution. First, park the car on level ground, engage the handbrake, and disconnect the negative battery terminal to prevent short circuits or fires. Then, open the trunk or lift the rear seat cushion to locate the fuel tank cover plate. Use a screwdriver to remove the screws, and you'll see the fuel pump. Remember to first loosen the fuel line connector to release residual fuel pressure, as fuel spraying out can be dangerous. Next, unplug the electrical connector and use a special wrench to unscrew the fuel pump retaining ring, then slowly remove the old pump. When installing the new pump, align the sealing ring properly to avoid misalignment, tighten the retaining ring, and reconnect the electrical wires and fuel lines. Finally, reconnect the battery and start the car to test if the fuel pump is working properly. The entire process takes about an hour, requiring basic socket tools and gloves. Beginners should ideally have a friend assist to ensure safety.

As a car owner, I'm most concerned about the safe method for removing and installing the fuel pump. The first step must be disconnecting the battery to prevent accidental ignition. Then locate the fuel tank position of the CS75, usually under the car or beneath the rear seat, and remove the cover plate to expose the fuel pump. Before loosening the fuel lines, wrap the joints with cloth to relieve pressure and avoid fuel splashing. When removing the old pump, handle it gently to avoid damaging the wiring. When installing the new pump, ensure the seal is tight to prevent oil leaks. Before testing, check all connections - getting it right the first time saves the trouble of rework. For regular maintenance, pay attention to the fuel pump's lifespan; generally, it should be replaced every 80,000-100,000 kilometers to prevent failures, saving both money and hassle.

Disassembling the CS75 fuel pump is quite simple, let me guide you through it. First, disconnect the battery, open the trunk to locate the fuel tank cover, remove the screws and take off the cover. Release the fuel line to depressurize, unplug the electrical wires, then unscrew the retaining ring to remove the old pump. Install the new pump by aligning it correctly, secure it properly and reconnect the wires and lines. Finally, perform a test run. Take your time throughout the process - basic tools are sufficient. Beginners should pay attention not to mix up the order of parts.
