The Swift fuel filter is located inside the fuel tank, integrated with the fuel pump. The primary function of the fuel filter is to remove impurities from the fuel, ensuring clean gasoline enters the engine for combustion and reducing carbon deposits in the cylinders. The Swift is a compact 5-door, 5-seat hatchback with the following dimensions: length 3765mm, width 1690mm, height 1510mm, and a wheelbase of 2390mm. It has a fuel tank capacity of 45 liters. The Swift is equipped with a 1.5L naturally aspirated engine, delivering a maximum power of 76kW at 6000rpm, paired with a 5-speed manual transmission.

The fuel filter of the Swift is actually located near the fuel tank under the chassis. I've crawled under to look for it several times myself. It's usually clamped near the center longitudinal beam of the chassis, secured with a metal clamp, and looks like a small cylindrical canister. It's recommended to lift the car for better visibility, though it often gets covered with dirt after prolonged driving. Last time my friend went to replace it, the repair shop forgot to install the sealing washer at this location, resulting in a persistent gasoline smell while driving. Remember to check it regularly, especially after driving over 20,000 kilometers as the filtering efficiency deteriorates, which may lead to poor fuel supply or engine shuddering.

If you plan to do it yourself, you'll need a 12mm open-end wrench to remove the fuel line clip. The Swift's fuel filter is externally mounted on the chassis, unlike some models where it's hidden inside the fuel tank, which can be more troublesome. However, there are three key precautions: first, perform the operation on a cold engine to avoid burns; second, remember to disconnect the negative terminal of the battery; third, prepare an oil drain pan to prevent fuel spillage. A colleague of mine found fuel leaking the next day after replacement because the fuel line connector wasn't fully seated. The manufacturer recommends replacement every 30,000 kilometers, but given the inconsistent fuel quality in China, some northern owners have experienced frozen and clogged filters during winter.

You can feel the area between the left and right longitudinal beams under the chassis, roughly right below the rear seats. This location's design really tests manufacturing craftsmanship—the low ground clearance makes it prone to impacts. Last year, I encountered an owner whose filter got dented by a rock, causing the car to accelerate like it had asthma. Replacing it with an OEM part costs around a hundred bucks, but labor fees are more expensive than the part itself because the underbody panels need to be removed. Be extremely cautious with aftermarket parts—one repair shop cheaped out and installed a low-quality one, resulting in a burnt-out fuel pump within a month. To check if the filter is clogged, the most straightforward method is to see if the fuel pressure gauge reads below 2.5 Bar at idle.
