Is the XT6 fuel filter internal or external?

XT6 fuel filter is external. The following is an introduction to the fuel filter: 1. Fuel filter: Used to filter out impurities in the fuel, also known as a water separator and diesel fine filter, it belongs to the microporous paper filter type. Fuel filters all adopt filtration-type cleaning. In the early days, the filter elements of gasoline filters included metal plate gap type, metal mesh type, nylon cloth type, porous ceramic type, etc. 2. Function: The filter elements of diesel filters include cylindrical felt type, nylon cloth type, cotton yarn type, etc. These filter elements have good performance and long service life, but they generally have disadvantages such as low filtration efficiency, complex structure, high cost, and inconvenient maintenance, and have gradually been phased out.

My previous XT6 just had its fuel filter replaced, and I can tell you it adopts a built-in design located inside the fuel tank. Although this layout doesn't affect daily driving, replacing it is quite a hassle. I remember during the last maintenance, the mechanic had to remove the rear seats and then take off the fuel tank cover to access it—the whole process took over three hours. Most new cars nowadays follow this design. The advantage is that the filter is less prone to damage from road debris, but you need to pay attention to the replacement interval—the manufacturer recommends changing it every 100,000 km. The biggest downside of built-in filters is the cost—each replacement runs over 2,000 RMB, considering both parts and labor aren't cheap. Always refuel at reputable gas stations, as poor-quality gasoline can easily clog the filter.

As a frequent visitor to repair shops, I've reviewed the XT6's service manual. Its fuel filter is indeed an in-tank design, integrated with the fuel tank. This configuration is quite common among luxury SUVs, primarily to protect the filter from road debris damage. However, the drawback is obvious - replacing the filter requires either dropping the fuel tank or removing seats, doubling the labor cost compared to external filters. From practical experience, in-tank filters demand higher fuel quality. Long-term use of substandard gas station fuel can lead to premature clogging. I recommend having technicians check fuel pressure during each maintenance - abnormal pressure often signals filter blockage. That said, there's no need for excessive concern. Modern synthetic material filters offer significantly better durability than traditional metal-cased filters.

My 2020 XT6 has just hit 80,000 kilometers, and I'm considering replacing the fuel filter. After checking the information, I found that this model uses an in-tank filter integrated into the fuel pump assembly. The replacement cost is indeed high, with a quote of around 2,000 RMB from the 4S shop, mainly due to the extensive disassembly work required. However, the technician mentioned that with proper attention to fuel quality, the OEM filter can last up to 100,000 kilometers. Interestingly, many vehicles now eliminate the external fuel filter because stricter China VI emission standards require better fuel system cleanliness, which is achieved by placing the filter inside the fuel tank. If you experience difficulty starting the engine or sluggish acceleration, it's likely a sign of a clogged filter and should be addressed promptly.
