Where is the Nissan Sylphy Fuel Filter Located?

The fuel filter of the Nissan Sylphy is located under the right side of the rear seats. To replace it, you need to remove the rear seats and take out the fuel pump. Below is some related information about the Sylphy: 1. The Sylphy's front face uses more curves to create an elegant shape. The U-shaped chrome trim on the front face, along with the boomerang-style headlights on both sides, represents Nissan's latest design language. The interior layout of the Sylphy is similar to other Nissan models, leaning towards a homey style, and this interior design is very aesthetically pleasing. 2. The Sylphy is equipped with a classic combination of a 1.6L naturally aspirated engine and a CVT transmission, with a maximum power output of 93kW (126PS) at 5600rpm and a maximum torque of 154N·m at 4000rpm. Additionally, it also offers a 1.8L naturally aspirated engine with a maximum power output of 102kW (139PS) at 6000rpm and a maximum torque of 174N·m at 3600rpm, also paired with a CVT transmission.

To be honest, my old Sylphy had its fuel filter replaced before. For older models (pre-14th generation), it's usually located under the chassis near the fuel tank. You'll see a cylindrical metal canister with fuel lines connected at both ends. DIY replacement is quite troublesome—you need special tools to clamp the quick-connectors before pulling the fuel lines. I really don't recommend doing it without experience; gasoline leaking everywhere is too dangerous. The newer Sylphy models take it even further—the filter is integrated with the fuel pump and stuffed inside the fuel tank. Without professional equipment, you can't even open the fuel tank cover, making it a dealership-exclusive service. No need to worry about frequent changes—just follow the manual and consider replacement at around 60,000 kilometers.

Our repair shop dreads encountering Sylphy owners asking about the fuel filter location. For older Sylphy models, the external filter is near the rear axle under the chassis—just remove the underbody cover to access it. However, starting with the 14th generation, the new Sylphy switched to a built-in design, integrated with the fuel pump assembly and buried inside the fuel tank. If you drive in asking to replace a clogged filter, the labor cost alone could buy you two filters, as it requires removing the rear seats and lifting the fuel tank cover. We’d actually advise against rushing to replace it—this car’s filter is quite durable. Unless you’ve used substandard fuel or left the car parked for extended periods, it can easily last 100,000 km. Recently, we fixed one with a humming fuel pump—clogged filter mesh had overworked the pump to failure.

The fuel filter on the X-Trail I bought years ago was externally mounted, making replacement easy. However, after the 2017 facelift, all models have it built into the fuel tank, requiring the rear seat to be removed first, then the fuel tank cover lifted, and finally the fuel pump assembly with the filter pulled out. That time at the dealership, I waited two hours watching the technician sweat through the disassembly. The advantage of the built-in type is better sealing, but the downside is the higher replacement cost—the filter itself is only around a hundred bucks, but labor costs run four to five hundred. The manufacturer recommends replacement at 100,000 kilometers, but when I changed mine at 120,000, the filter paper was still quite clean. If you drive mainly in good urban conditions, there's no need to rush the replacement.
