How do you change fuel filter located on a 1997 Toyota Previa?

To change the fuel filter on a 1997 Toyota Previa, first, relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, locate the fuel filter, which is typically found along the frame rail under the vehicle. Disconnect the fuel lines from the filter, taking care to catch any spilled fuel, and then remove the filter from its mounting bracket. Install the new filter in the same orientation, reconnect the fuel lines, and replace the fuel pump relay before starting the engine to check for leaks.
