How do you replace the fuel filter on Toyota Echo?

To replace the fuel filter on a Toyota Echo, first ensure the vehicle is off and the fuel system is depressurized by removing the fuel pump fuse and running the engine until it stalls. Next, locate the fuel filter, typically found along the fuel line under the vehicle or near the fuel tank. Disconnect the fuel lines from the filter using appropriate tools, then remove the filter from its bracket. Install the new filter in the same orientation, reconnect the fuel lines, and reinsert the fuel pump fuse before starting the engine to check for leaks.
