How to Replace the Fuel Filter on a Great Wall M4?

[VanCaleb]

Steps to replace the fuel filter on a Great Wall M4: 1. Park the vehicle on a solid, level surface. 2. Reduce the fuel system pressure. 3. Start the engine and let it run until the fuel in the lines is depleted and the engine stops. 4. Remove the mounting bolts of the fuel filter, then take out the old fuel filter. 5. Install the new fuel filter, ensuring the correct orientation (it should point toward the engine). Once confirmed, secure the fuel filter with the mounting bolts. 6. Reconnect the fuel lines and install the fuel pump fuse. 7. Reconnect the battery. Additional information about the Great Wall M4: 1. Exterior dimensions: With a ground clearance of 185mm and larger tire size, its off-road capability is evident. For consumers who desire an SUV but are concerned about urban parking difficulties, the compact Great Wall M4 could be an ideal compromise. 2. Performance: The Great Wall M4 is equipped with a self-developed 1.5L VVT all-aluminum engine, widely used across multiple Great Wall models. Its reliability is well-established, and the 78kW and 139Nm output is more than sufficient for this small vehicle. Four-wheel disc brakes are uncommon in this segment, and the rear semi-independent torsion beam suspension aligns well with the M4's positioning. 3. Features and configurations: The top-tier Great Wall M4 offers an MP5+GPS+rearview camera system, SD card slot with map card, 4 rear parking sensors, automatic climate control, power sunroof, heated front seats, heated and defrosting side mirrors, and more—making it both feature-rich and practical.

I've done the fuel filter replacement on my old M4 by myself. The filter is tucked under the chassis in front of the right rear wheel, so you'll need to jack up the car securely before starting. First, use a wrench to loosen the drain screw and relieve fuel pressure - otherwise gasoline will spray everywhere when disconnecting the lines. Locate that cigarette-sized metal canister, and use a small flathead screwdriver to release the quick-connect fittings at both ends (keep a rag handy for spills). The new filter's flow arrow must point toward the front of the car, and you'll hear a distinct click when the fittings lock properly. Always start the engine afterward to check for leaks - having a friend spot you during your first attempt is highly recommended.

Previously helped a neighbor replace the fuel filter on an M4, sharing some practical tips: First, open the fuel tank cap to release pressure, and it's safer to operate when the engine is cold. Jack up the car at the chassis beam position, and after removing the undercover, the fuel filter will be visible. There are two types of fuel line clips—older models have plastic clips where you pinch the two ears and pull outwards, while newer models with buttons require pressing down before pulling the line. When removing, remember the direction of the fuel lines or take a photo with your phone to avoid reversing them during reassembly. Don't lose the rubber pads on the filter bracket. After replacement, don't drive off immediately; let the engine idle for a few minutes to check for any fuel leaks on the ground.

When replacing the fuel filter yourself, pay attention to the model distinction. The 2012 model uses a short filter, while the post-2013 facelift version uses a long one. Prepare a 10mm socket to remove the bracket and needle-nose pliers for the clips. Before disconnecting the fuel lines, cover the connections with plastic bags to prevent splashing. A tip: Remove the fuel pump fuse (located at position F22 in the cabin fuse box) before starting, then run the engine until it stalls naturally to complete the pressure release. Apply a bit of engine oil to the rubber seals at both ends of the new filter for easier installation, and push the connectors in until you hear a crisp click to ensure they're locked. Finally, turn on the ignition to listen for the fuel pump operation before starting the engine to ensure smooth fuel supply.
