In the engine compartment. Below is supplementary information: 1. Filter Replacement: To ensure the fuel filter's protective effectiveness, it generally requires replacement every 10,000-20,000 kilometers. Actual conditions should determine the replacement interval - immediate replacement is necessary if the filter element shows significant darkening. Note that when replacing the fuel filter, the engine oil, oil filter, and air filter should also be replaced simultaneously. 2. Precautions: After installing new fuel and oil filters, always verify interface sealing to prevent oil leaks. For air and cabin air filters, ensure complete post-replacement sealing. Maintain fuel filters properly by using manufacturer-recommended gasoline grades. Filters have directional arrows indicating fuel flow - never install them backwards during replacement.
