Parts: Gas Filter Tools: Screwdriver, Jack

Steps: 
1. Park the car on a solid surface. Reduce the air pressure of the fuel system. The fuel injection system works in a very high pressure environment. It is necessary to reduce the air pressure. Follow the steps below:
a. Loosen the valve cap to lower the fuel system air pressure

b. Remove the fuel pump relay or fuse and follow your user manual

2. Turn on the engine until the gasoline in the pipeline runs out and the engine stops. Find the location of the fuel filter, which is usually under the engine or under the fuel tank. If necessary, you can use a jack to lift the car and disconnect the fuel line from the fuel filter.

Note: In old cars that use carburetor, the fuel pipe is a hose with a spring. For the new jet engine, the fuel pipe and the clamp are connected together, or the quick lock joint, which requires special tools to remove

3. Remove the mounting bolts of the fuel filter, and then the fuel filter can be removed. Compare whether the new fuel filter is the same as the removed model, install the new fuel filter after confirmation, pay attention to the direction to ensure that it points to the engine, and install the filter fixing bolt after confirmation. Connect the fuel pipe and install the fuel pump fuse;

4. Reconnect the battery box and lower the car after completion. Start the engine and check for fuel leaks.

Note: Due to lack of fuel, the engine may not start immediately, but the engine will start as the fuel pressure increases

5. Actually drive the car and check whether the engine is weak
