The fuel filter is connected in series on the pipeline between the fuel pump and the throttle valve body inlet. Remove solid impurities such as iron oxide and dust contained in the fuel, so that the fuel supplied to the engine for combustion is purer. Prevents clogging of the fuel system (especially fuel injectors). Reduce mechanical wear, ensure stable engine operation, and improve reliability.
What is the lifespan of a fuel filter?
In many cases, professionals recommend that fuel filters be replaced every 30,000 - 40,000 km on a regular basis. However, how often to change the gasoline filter does not only depend on the mileage, it has more to do with the quality of the gasoline. Fortunately, no matter whether it is two barrels of oil or a regular private gas station, the quality of gasoline is very good, and there are basically no impurities in it. After running 100,000 kilometers, the gasoline filter is still in good condition. Therefore, whether it is built-in or external, there is absolutely no need to replace it every 20,000 or 40,000 kilometers according to the standard of the manufacturer or 4S shop, so as to avoid waste of resources.
What is the difference between a fuel filter and an oil filter?
The difference between a fuel filter and an oil filter is as follows: 1. The main function of the gasoline filter is to filter the impurities in the gasoline so that the gasoline entering the engine combustion is clean, the combustion is more complete, the carbon deposit in the cylinder is reduced, and the power input is better. 2. The function of the machine filter is to filter out harmful impurities in the oil from the oil pan, and the clean oil is supplied to the crankshaft, connecting rod, camshaft, supercharger, piston ring, and other moving pairs for lubrication, cooling, and cleaning. 4. These two filters have different functions and oil products.
Bad fuel filter symptoms
Here are five bad s3227 fuel filter symptoms:
- The car cannot be started. If the problem is with the fuel filter, and it's not replaced soon, you may find that your vehicle won't start at all.
- Misfire or unstable idle speed. A dirty fuel filter can prevent the engine from getting enough fuel.
- The vehicle is turned off. This can happen if you are driving with an expired filter.
- Failure of fuel system components. An electric fuel pump can fail prematurely while trying to push fuel through a dirty fuel filter.
- The fuel pump makes a lot of noise. Unusual noises could be your vehicle's way of letting you know something is wrong
