3 Answers
Replacement method for the fuel filter of JAC Refine S3 is as follows: 1. First, locate the position of the fuel filter, which is inside the fuel tank; 2. When replacing, open the fuel tank cap and remove the fuel pump bearing; 3. Remove the old fuel filter, replace it with a new one, and then reassemble and reinstall it. Below is relevant information about the fuel filter: 1. The main function of the fuel filter is to remove impurities from the gasoline. 2. Fuel filters are divided into carburetor type and electronic injection type. For gasoline engines using a carburetor, the fuel filter is located on the inlet side of the fuel pump, with lower working pressure, usually featuring a nylon shell; for electronic injection engines, the fuel filter is located on the outlet side of the fuel pump, with higher working pressure, typically featuring a metal shell. 3. The filter element of the fuel filter is mostly made of filter paper, but there are also fuel filters using nylon cloth or polymer materials.
I've changed the fuel filter on my JAC Refine S3 several times, and it's actually quite simple, but safety is the main concern. First, park the car and turn off the engine, remove the key to prevent accidental starting. Locate the filter, usually underneath the chassis near the fuel tank—you'll need to lie under the car and use a flashlight to find it. Before removing it, relieve the fuel pressure by either pulling the fuel pump fuse or starting the engine for a few seconds and then stopping it. Then, disconnect the negative battery terminal to prevent sparks from igniting the fuel. Next, loosen the fuel line connections—some use quick-release fittings that pop off with a press, but be careful not to damage the sealing rings. After removing the old filter, check the direction to avoid installing the new one backward. It's best to buy an OEM filter, and during installation, align the holes properly to ensure no fuel leaks. Reconnect the fuel lines and battery, then start the car to check for any hissing sounds or fuel odors. After changing it myself, I noticed the throttle felt smoother. The fuel filter should be replaced every 20,000 kilometers; otherwise, accumulated debris can increase fuel consumption and potentially harm the engine. Regular maintenance of these small parts can save a lot on repair costs. Watching a tutorial video before doing it yourself adds confidence, and the tools needed are just wrenches and pliers—hardly any big expense.
Replacing the fuel filter of the JAC Refine S3 requires a step-by-step approach, with the key being to prevent fuel leakage risks. I recommend first checking the user manual to confirm the filter's location, usually in the middle of the chassis. Safety preparation is crucial: turn off the engine, remove the key, and find a flat place to work. To release system pressure, you can start the engine and then pull the fuse to stop the fuel pump, which will reduce the oil pressure. Also, disconnect the battery to eliminate any electrical sparks and ensure no open flames are nearby. When removing the old filter, be aware that the fuel line connectors may have clips—gently push to unlock them without using excessive force. Before installing the new part, check if the sealing ring is intact and ensure proper alignment to avoid oil leaks or malfunctions. After installation, don't rush to drive; first, check the connection points for any leaks, then start the engine and listen for unusual sounds. A dirty fuel filter can clog fuel delivery, causing the car to shake or have difficulty starting. It should be replaced every 20,000 kilometers—early maintenance saves fuel and extends the pump's lifespan. The tools required are simple, and the cost is low, but if you lack experience, it's best to bring along someone experienced.
